HubL filters - HubSpot docs

Last modified: August 22, 2025

Filters affect the ultimate output of your HubL. They can be applied to various HubL statements and expressions to alter the template markup outputted by the server. The basic syntax of a filter is |filtername. The filter is added directly following the statement or the expression, within its delimiters. Some filters have additional parameters that can be added in parentheses. The basic syntax of a filter with a string, a number, and a boolean parameters is: |filtername("stringParameter", 10, true). Notice that string parameters should be written in quotes. Also note that HubL filters have an alias that can be used to serve the same purpose as the primary filter. The following article contains all of the supported HubL filters.

Please note:You can apply HubL filters to personalization tokens, such as contact and company tokens, on HubSpot CMS and blog pages, but not in emails.

abs

Gets the absolute value of a number. You can use this filter to ensure that a number is positive.

{% set my_number = -53 %}
{{ my_number|abs }}

add

Adds a numeric value to another numeric value. This filter functions the same as the + operator. The parameter in parentheses is the addend that you are combining with your initial numeric value.

{% set my_num = 40 %}
{{ my_num|add(13) }}

attr

Renders the attribute of a dictionary. This filter is the equivalent of printing a variable that exists within a dictionary, such as content.absolute_url.

{{ content|attr("absolute_url") }}

Parameter	Description
`attribute_name`	Specifies which attribute to print.

batch

Groups items within a sequence. In the example below, there is a variable containing a sequence of types of fruits. The batch filter is applied to a loop that iterates through the sequence. The nested loop runs three times to print 3 types of fruit per row, before the outer loop runs again. Notice in the final output that since there are only 5 types of fruit, the final item is replaced by a   (the second parameter).

{% set rows = ["apples", "oranges", "pears", "grapes", "blueberries"] %}

<table>
{% for row in rows|batch(3, " ") %}
<tr>
{% for column in row %}
<td>{{ column }}</td>
{% endfor %}
</tr>
{% endfor %}
</table>

Parameter	Type	Description
`linecount`	Number	The number of items to include in the batch.
`fill_with`	String	Specifies what to include in order to fill up any missing items.

between_times

Calculates the time between two datetime objects in a specified time unit.

Please note:You should use this filter only with variables that return a date. Starting September 30, 2024, this filter will no longer return the current date when a null value is passed. After that date, a null value in the filter will return September 30, 2024.

{% set begin = "2018-07-14T14:31:30+0530"|strtotime("yyyy-MM-dd'T'HH:mm:ssZ") %}
{% set end = "2018-07-20T14:31:30+0530"|strtotime("yyyy-MM-dd'T'HH:mm:ssZ") %}
{{ begin|between_times(end, "days") }}

Parameter	Type	Description
`end`	datetime object	The ending datetime object.
`timeunit`	String	Valid time units are `nanos` , `micros` , `millis` , `seconds` , `minutes` , `hours` , `half_days` , `days` , `weeks` , `months` , `years` , `decades` , `centuries` , `millennia` , and `eras` .

bool

Converts a text string value to a boolean.

{% if "true"|bool == true %}hello world{% endif %}

capitalize

Capitalizes the first letter of a variable value. The first character will be uppercase, all others letters will be lowercased. Subsequent words separated by spaces or hyphens will not have their first letter uppercased.

{% set sentence = "the first letter of a sentence should always be capitalized." %}
{{ sentence|capitalize }}

center

Centers text within a given field length using whitespace. This filter is not recommended or particularly useful since HubSpot’s HTML compiler will automatically strip out the white space; however, it is included here for the sake of comprehensiveness. The example below shows this filter being applied to a variable in a pre tag, so the whitespace isn’t stripped out.

<pre>
{% set var = "string to center" %}
before{{ var|center(80) }}after
</pre>

Parameter	Type	Description
`width`	Number	Specifies the length of whitespace to center the text in.

convert_rgb

Converts a HEX value to an RGB string. This is useful if you need to convert color variables to RGB to be used with a RGBA CSS declaration. In the example below, the value set by a color module is converted to an RGB value and used in an RGBA CSS declaration.

{% set my_color = "#FFFFFF" %}
{{ my_color|convert_rgb }}
{% set my_color2="#000000" %}
<div style="background: rgba({{ my_color2|convert_rgb }}, .5)"></div>

cut

Removes a string from a value. This filter can be used to match and cut out a specific part of a string. The parameter specifies the part of the string that should be removed. The example below removes the space and the word world from the original variable value.

{% set my_string = "Hello world." %}
{{ my_string|cut(" world") }}

Parameter	Type	Description
`characters_to_cut`	String	The part of the string that should be removed.

datetimeformat (deprecated)

Please note:This filter has been deprecated. Instead, use the format_datetime filter, which has a more standardized syntax.

default

If the value is undefined it will return the first parameter, otherwise the value of the variable will be printed. If you want to use default with variables that evaluate to false, you have to set the second parameter to true. The first example below would print the message if the variable is not defined. The second example applies the filter to an empty string, which is not undefined, but it prints a message due to the second parameter.

{{ my_variable|default("my_variable is not defined") }}
{{ ""|default("the string was empty", true) }}

Parameter	Type	Description
`default_value`	String	The value to return if the variable is undefined. If the variable is defined, the value of the variable will be returned instead.
`truthy`	Boolean	Set to `true` to use with variables which evaluate to `false`.

dictsort

Sort a dict and yield (key, value) pairs. Dictionaries are unsorted by default, but you can print a dictionary, sorted by key or value. The first parameter is a boolean to determine, whether or not the sorting is case sensitive. The second parameter determines whether to sort the dict by key or value. The example below prints a sorted contact dictionary, with all the known details about the contact.

{% for item in contact|dictsort(false, "value") %}
{{item}}
{% endfor %}

Parameter	Type	Description
`case_sensitive`	Boolean	Determines if sorting is case sensitive.
`sort_by`	`"key"` \| `"value"`	Determines whether to sort by `key` or `value`.

difference

Returns the difference of two sets or lists. The list returned from the filter contains all unique elements that are in the first list but not the second.

{{ [1, 2, 3]|difference([2, 3, 4, 5]) }}

Parameter	Type	Description
`list`	Array	The second list to compare to for use in finding differences from the original list.

divide

Divides the current value by a divisor. The parameter passed is the divisor. This filter is an alternative to the / operator.

{% set numerator = 106 %}
{{ numerator|divide(2) }}

Parameter	Type	Description
`divisor`	Number	The number to divide the variable by.

divisible

An alternative to the divisibleby expression test, this filter will evaluate to true if the value is divisible by the given number.

{% set num = 10 %}
{% if num|divisible(2) %}
The number is divisible by 2
{% endif %}

Parameter	Type	Description
`divisor`	Number	The number to use when evaluating if the value is divisible.

escape_html

Escapes the content of an HTML input. Accepts a string and converts the characters &, <, >, ‘, ”, and escape_jinjava into HTML-safe sequences. Use this filter for HubL variables that are used in HTML but should not allow any HTML.

{% set escape_string = "<div>This markup is printed as text</div>" %}
{{ escape_string|escape_html }}

escape_attr

Escapes the content of an HTML attribute input. Accepts a string and converts the characters &, <, ‘, ”, and escape_jinjava into HTML-safe sequences. Use this filter for HubL variables that are being added to HTML attributes. Note that when escaping values of attributes that accept URLs, such as href, you should use the escape_url filter instead.

{% set escape_string = "This <br> markup is printed as text" %}
<img src="test.com/imageurl" alt="{{escape_string|escape_attr}}">

escape_jinjava

Converts the characters { and } in strings to Jinjava-safe sequences. Use this filter if you need to display text that might contain such characters in Jinjava.

{% set escape_string = "{{This markup is printed as text}}" %}
{{ escape_string|escape_jinjava }}

escape_js

Escapes strings, including escape_jinjava, so that they can be safely inserted into a JavaScript variable declaration. Use this filter for HubL variables that are used inside HTML script elements.

{% set escape_string = "\tThey said 'This string can safely be inserted into JavaScript.'" %}
{{ escape_string|escape_js }}

escape_url

Escapes the content of a URL input, enforcing specified protocols, stripping invalid and dangerous characters, and encoding HTML entities. Returns empty if a URL is valid. Use this filter for HubL variables that are used within HTML attributes that should be valid URLs.

{% set escape_string = "http://example.com/with space/<html>" %}
<a href="https://developers.hubspot.com/docs{{ escape_string|escape_url }}"></a>

escapejson

Escapes strings so that they can be used as JSON values.

{% set escape_string = "<script>alert('oh no!')</script>" %}
{% require_js position="head" %}
<script data-search_input-config="config_{{ name }}" type="application/json">
{
"autosuggest_results_message": "{{ escape_string|escapejson }}"
}
</script>
{% end_require_js %}

filesizeformat

{% set my_text="25" %}
{{ my_text|float + 17 }}

Parameter	Type	Description
`default`	Number	Integer to return if the conversion doesn’t work.

forceescape

Strictly enforces HTML escaping. In HubSpot’s environment there isn’t really a use case for double escaping, so this is generally behaves the same as the escape filter.

{% set escape_string = "<div>This markup is printed as text</div>" %}
{{ escape_string|forceescape }}

format

Applies Python string formatting to an object. %s can be replaced with another variable.

The basic usage is mapping on an attribute. For example, if you want to use conditional logic to check if a value is present in a particular attribute of a dict. Alternatively, you can let it invoke a filter by passing the name of the filter and the arguments afterwards.

{# Usage 1 #}
Apply a filter to a sequence:
{% set seq = ["item1", "item2", "item3"] %}
{{ seq|map("upper") }}

{# Usage 2 #}

Converts a different variable type to a string. In the example below, a integer is converted into a string (pprint is used to confirm the change in variable type).

{% set number_to_string = 45 %}
{{ number_to_string|string|pprint }}

striptags

Strips SGML/XML tags and replace adjacent whitespace by one space. This filter can be used to remove any HTML tags from a variable.

{% set some_html = "<div><strong>Some text</strong></div>" %}
{{ some_html|striptags }}

strtodate

Converts a date string and date format to a date object.

{{ '3/3/21'|strtodate('M/d/yy') }}

Parameter	Type	Description
`dateFormat`	String	The date format to use.

strtotime

Converts a datetime string and a datetime format into a datetime object.

{{ "2018-07-14T14:31:30+0530"|strtotime("yyyy-MM-dd'T'HH:mm:ssZ")|unixtimestamp }}

Parameter	Type	Description
`datetimeFormat`	String	The Date and time format to use.

sum

Adds numeric values in a sequence. The first parameter can specify an optional attribute and the second parameter sets a value to return if there is nothing in the variable to sum.

// Simple sum
{% set sum_this = [1, 2, 3, 4, 5] %}
{{ sum_this|sum }}

// Sum of attribute
{% set items = [15, 10] %}
{% set dict_var = [{"name": "Item1", "price": "20"}, {"name": "Item2", "price": "10"}] %}
Total: {{ dict_var|sum(attribute="price") }}

Parameter	Type	Description
`attribute`	String	Attribute to sum.
`return_if_nothing`	String	Value to return if there is nothing in the variable to sum.

symmetric_difference

Returns the symmetric difference of two sets or lists. The list returned from the filter contains all unique elements that are in the first list but not the second, or are in the second list but not the first.

{{ [1, 2, 3]|symmetric_difference([2, 3, 4, 5]) }}

Parameter	Type	Description
`list`	Array	The second list to compare to for use in finding the symmetric difference with the original list.

title

Returns a title case version of the value (i.e., words will start with uppercase letters but all remaining characters are lowercase).

{% set my_title="my title should be title case" %}
{{ my_title|title }}

tojson

Writes an object as a JSON string.

{% for content in contents %}
{{ content.blog_post_author|tojson }}
{% endfor %}

trim

Strips leading and trailing whitespace. HubSpot already trims whitespace from markup, but this filter is documented for the sake of comprehensiveness.

{{ " remove whitespace " }}
{{ " remove whitespace "|trim }}

truncate

Cuts off text after a certain number of characters. The default is 255. HTML characters are included in this count.

Please note:Because this filter relies on the spaces between words to shorten strings, it may not work as expected for languages without spaces between characters, such as Japanese.

{{ "I only want to show the first sentence. Not the second."|truncate(40) }}
{{ "I only want to show the first sentence. Not the second."|truncate(35, true, "..........") }}

Parameter	Type	Description
`number_of_characters`	Number	Number of characters to allow before truncating the text. Default is 255.
`breakword`	Boolean	If `true`, the filter will cut the text at length. If `false`, it will discard the last word.
`end`	String	Override the default ’…’ trailing characters after the truncation.

truncatehtml

Truncates a given string, respecting HTML markup (i.e. will properly close all nested tags). This will prevent a tag from remaining open after truncation. HTML characters do not count towards the character total.

Please note:Because this filter relies on the spaces between words to shorten strings, it may not work as expected for languages without spaces between characters, such as Japanese.

{% set html_text = "<p>I want to truncate this text without breaking my HTML<p>" %}
{{ html_text|truncatehtml(28, "..." , false) }}

Parameter	Type	Description
`number_of_characters`	Number	Number of characters to allow before truncating the text. Default is 255.
`end`	String	Override the default ’…’ trailing characters after the truncation.
`breakword`	Boolean	Boolean value. If `true`, the filter will cut the text at length. If `false` (default), it will discard the last word. If using only one of the optional parameters, use keyword arguments, such as `truncatehtml(70, breakwords = false)`.

unescape_html

Converts text with HTML-encoded entities to their Unicode equivalents.

{% set escape_string = "me & you" %}
{{ escape_string|unescape_html }}

union

Returns the union of two sets or lists. The list returned from the filter contains all unique elements that are in either list.

{{ [1, 2, 3]|union([2, 3, 4, 5]) }}

Parameter	Type	Description
`list`	Array	The second list to union with the original list.

unique

Extracts a unique set from a sequence or dict of objects. When filtering a dict, such as a list of posts returned by a function, you can specify which attribute is used to deduplicate items in the dict.

{% set my_sequence = ["one", "one", "two", "three" ] %}
{{ my_sequence|unique }}

Parameter	Type	Description
`attr`	String	Specifies the attribute that should be used when filtering a dict value.

unixtimestamp

Converts a datetime object into a Unix timestamp.

{{ local_dt }}
{{ local_dt|unixtimestamp }}

upper

Converts all letters in a value to uppercase.

{% set text="text to make uppercase" %}
{{ text|upper }}

urlencode

Escapes and URL encodes a string using UTF-8 formatting. Accepts both dictionaries and regular strings as well as pairwise iterables.

{% set encode_value="Escape & URL encode this string" %}
{{ encode_value|urlencode }}

urldecode

Decodes encoded URL strings back to the original URL. Accepts both dictionaries and regular strings as well as pairwise iterables.

{% set decode_value="Escape+%26+URL+decode+this+string" %}
{{ decode_value|urldecode }}

urlize

Converts URLs in plain text into clickable links. If you pass the filter an additional integer it will shorten the urls to that number. The second parameter is a boolean that dictates whether the link is rel="no follow". The final parameter lets you specify whether the link will open in a new tab.

{{ "http://hubspot.com/"|urlize }}
{{ "http://hubspot.com/"|urlize(10,true) }}
{{ "http://hubspot.com/"|urlize("",true) }}
{{ "http://hubspot.com/"|urlize("",false,target="_blank") }}

Parameter	Type	Description
`shorten_text`	Number	Integer that will shorten the urls to desired number.
`no_follow`	Boolean	When set to `true`, the link will include `rel="no follow"`.
`target="_blank"`	String	Specifies whether the link will open in a new tab.

wordcount

Counts the number of words in a string.

If the string contains HTML, use the striptags filter to get an accurate count.

{%  set count_words = "Count the number of words in this variable"  %}
{{ count_words|wordcount }}

wordwrap

Causes words to wrap at a given character count. This works best in a <pre> because HubSpot strips whitespace by default.

{% set wrap_text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Etiam efficitur, ipsum non sagittis euismod, ex risus rhoncus lectus, vel maximus leo enim sit amet dui. Ut laoreet ultricies quam at fermentum." %}
{{ wrap_text|wordwrap(10) }}

Parameter	Description
`character_count`	Number of characters to wrap the content at.

xmlattr

Creates an HTML/XML attribute string, based on the items in a dict. All values that are neither none nor undefined are automatically escaped. It automatically prepends a space in front of the item if the filter returned something unless the first parameter is false.

{% set html_attributes = {"class": "bold", "id": "sidebar"} %}
<div {{ html_attributes|xmlattr }}></div>

Parameter	Type	Description
`autospace`	Boolean	Set to `true` to add a space in front of the item.
