Text Functions

Text functions analyze or manipulate string data and are useful sanitizing string input.

When inputting a string, use quotation marks to indicate it as a string. “This is read as a string”

If you would like to include quotes in your string, you can use a slash \ to indicate the following quote is part of the string. “\”This is a string with quotes\”” will display as “This is a string with quotes”
