Text and Strings

Text manipulation and adjustments - How to work with text?

The easiest way to test your Jinja2 expressions is by using a Jinja2 evaluator with mock data (Don't include any sensitive data in those). Note, only standard Jinja2 expressions will work here, like if, elif, upper, etc.

Making strings UPPER case

{% set my_text = 'This will be upper case!' %}
{{ my_text | upper }}

Returns: THIS WILL BE UPPER CASE!

Making strings lower case

{% set my_text = 'This will be upper case!' %}
{{ my_text | lower }}

Returns: this will be lower case!

Concatenating Strings

{{ '+49', '292828834'   |   join(' ')   }} 

--> Returns a space: [phone]

If you just want a joint without a string, you can just write:
{{ '+49', '292828834'   |   join   }} 

--> Returns a space: [phone]

Another common use-case is comma-separated concatenation:

{{  'BMW', 'Mercedes', 'Audi'   |   join(', ')   }} 

--> Returns: BMW, Mercedes, Audi

Limiting or shortening strings to a certain number of characters:

my_string = "Hello my nam is Max"

my_string[:5]
 --> Returns: Hello

my_string[:7]
 --> Returns: Hello m

FYI: my_string[:7] yields the same result as my_string[0:7]
