Extract data with Regex into a variable in RunMacro

What it does

The Extract Regex command uses a regular expression to pull a piece of data (OTP, email, number...) from a variable, text, or the clipboard, then stores it in a variable.

When to use it

Grab a 6-digit OTP from a message/email.
Pull an email or phone number from a block of text.
Isolate the needed data before using it.

Configuration steps

Add a Variables › Extract Regex command.
Choose the source (Variable / Text / Clipboard) and enter the source value.
Enter the regex pattern (e.g. \d{6} for 6 digits) and the result variable.
(Optional) choose the group/match index. Save.

Every option explained

Source + source value

Where to read the text: a variable, typed text, or the clipboard.

Regex pattern

The regular expression to match. Examples: \d{6}, [\w.]+@[\w.]+.

Group + match index

Group 0 = whole match; a number/name gets a captured group. Match index selects which match when several exist.

On no match

Choose to continue with an empty value, or treat it as a failure.

Extract-all mode (mode = all)

Instead of one result, capture every match into numbered variables var_1, var_2... plus a count variable (var_count). You can set an expected count to flag mismatches, and hide the values in the log.

Real example

Example: extract a 6-digit OTP from the clipboard

Copy the message containing the OTP.
Extract Regex: source Clipboard, pattern \d{6} → variable otp.
Use {otp} to fill the code field.

Tips & common mistakes

Test the pattern on an online regex tool first to be sure it matches the right part.
