Does this tool support Regular Expressions (RegEx)?

Yes. Enable the 'Regular Expression' toggle to use regex search patterns (e.g. \d{3}-\d{2}-\d{4} or ^https?://) and capture replacements.

Can I replace text in only one column?

Yes. Select any specific column from the target dropdown to restrict find-and-replace actions to that field only.

Is my data uploaded to an external server during search and replace?

No. All text parsing and string substitutions run strictly within your browser's local memory sandbox.
