Frequently Asked Questions
Quick answers to common questions about using this tool.
Does Find and Replace Text upload my text? +
No. Matching, preview, and replacement run locally in your browser. Your text and TXT files are not sent to PotatoTools.
Can I replace only one match? +
Yes. Use the match navigation controls to select a match, then choose Replace. Replace all changes every current match at once.
Can I review matches before changing the source? +
Yes. The live preview highlights matches without changing their text. Replacement text appears only after you choose Replace or Replace all.
Does regex support capture groups? +
Yes. Turn on Regex and use capture references such as $1 or $<name> in the replacement field. Invalid or slow patterns show an inline error and can be changed safely.
Can I undo a replacement? +
Yes. Undo and redo are available for applied replacements during the current browser session. History is not saved after you leave the page.
