Regular Expression

The Regular Expression action builds a regex value for other text actions. Use it with Matches Regex, Extract Text with Regex, Replace Text, Split Text, or Count Occurrences.

Inputs

Input	Type	Required	Description
Pattern	String	Yes	A non-empty JavaScript regular-expression pattern. Defaults to `.*`.
Flags	String	No	The selected regex flags. The node defaults to `ig`.

Flags

Flag	Setting	Effect
`g`	Global	Finds or replaces every match instead of only the first.
`i`	Ignore case	Matches letters without case sensitivity.
`m`	Multiline	Makes `^` and `$` work at line boundaries.
`s`	Dot-all	Allows `.` to match line-break characters.

Outputs

Output	Type	Description
Regex	Regular expression	The compiled pattern and selected flags.

Example: invoice IDs

Set Pattern to:

\bINV-\d{4}\b

Keep Global on to find every ID and Ignore case on if inv-1042 should also match. Connect Regex to Extract Text with Regex to return the matches.

Enter the pattern without wrapping / characters. For example, use \d+, not /\d+/g; choose flags separately. An invalid pattern fails when the action runs.

Replace TextReplace literal text or regex matches inside a string.
