Here you can find out more about the text functions in our apps!


The 'length("hello world")' function gives you the number of characters of the given text.

The 'letter(1,"hello world")' function gives you the letter from the given position. In this example it gives you the 'h' from 'hello world'.

The 'join("hello"," world") adds the two given strings/words to one. But don't forget the space in front of the second word or at the end of the first word! Otherwise you will get "helloworld".

The 'regular expression' formula is very powerful but also quite complex. See the Regular Expression page for details, explanations, further links, and examples.
