Find and replace text

FileGizmo finds and replaces literal words, phrases, or regular-expression matches without sending your text to a server. Paste the source text, enter what to find, and provide replacement text. Choose whether matching is case-sensitive and whether to replace the first occurrence or every occurrence, then review the read-only result before copying or downloading it.

Literal mode treats punctuation and symbols exactly as entered, which is the safest default for ordinary editing. Regex mode is available for structured changes and reports malformed expressions instead of silently changing the document. Replacement counts make the result easy to verify. Empty search values are rejected because matching every position would produce confusing output.

The work happens in a browser worker, keeping the editor responsive for larger notes, logs, code, and lists. Output is downloadable as UTF-8 plain text through FileGizmo’s standard result contract. Always review replacements involving names, identifiers, or source code because a technically correct global match can still change text you intended to keep.
