When you use data fields in different parts like saving email to a folder, or print email with fields, you can extract only a part of the data. That's useful when you have long string and want to get only a part like an email or an order number.
Example: You want to save email in a folder using the email unique id as part of folder or filename, but it is very long %22456464xcvrg4vcv@sgdcv12%, you want to keep only the last 4 digits so you can use the function: RIGHT(%EMAIL_ID%, 4).
The available functions are:
- LEFT(field,X) = extract the X number of characters from the start (for example LEFT("Order received from King of Flowers", 5) return "Order")
- RIGHT(field,X) = extract the X number of characters from the end (for example RIGHT("Order received from King of Flowers", 7) return "Flowers")
- MID(field,X,Y) = extract the Y number of characters from the X position (for example MID("Order received from King of Flowers", 6, 8) return "received")
- REGEX() = use regular expressions to extract data, this function is particular and requires some computer skills. For more information on RegEx please check these sites:
Here some basic examples to use REGEX in the fields: - Extract all numbers in the email subject field: REGEX(%EMAIL_SUBJECT%,([0-9]+)) - Exclude the characters #: in the attachment filename: REGEX(%FILENAME_FULL%,[^#]) - Exclude the characters FW: in subject of email: REGEX(%EMAIL_SUBJECT%,[^FW:])
