Bulk replace
Change every occurrence in one go, with a count of replacements.
Regex support
Use full regular expressions for advanced find-and-replace.
Free & private
Your text stays on your device.
Rename a variable across pasted code
Paste a function or config block and rename a variable, key, or string everywhere it appears in one pass. Turn on Match case so userId is renamed but UserID and userid are left untouched, and check the replacement count to confirm you caught every occurrence before copying the cleaned-up code back into your editor.
Reformat dates and numbers with regex
Switch on Use regex to rewrite patterns instead of fixed words. Match dates like (\d{4})-(\d{2})-(\d{2}) and reorder them to $3/$2/$1, or strip every phone number to digits only. Capture groups in the replacement field let you reshape thousands of rows of pasted data at once without writing a script or spreadsheet formula.
Scrub names from text before sharing
Paste a log, transcript, or email thread and replace real names, emails, account IDs, or API keys with placeholders like [REDACTED] before posting it publicly or to support. Because every replacement happens in your browser and nothing is uploaded, the sensitive original never leaves your device, and the live count tells you exactly how many instances were swapped out.
