Find and Replace
Find and replace text with optional regex and case sensitivity — shows match count live.
How to use this tool
- 1Paste text into the left Input panel.
- 2Enter your search term in the Find field and replacement in the Replace with field.
- 3Toggle Regex to use a regular expression pattern, and Case-sensitive to control case matching.
- 4The match count and replaced output update in real time — click Copy to copy the result.
About Find and Replace
This find-and-replace tool swaps every literal occurrence of a search string for a replacement in the text you paste. It is a quick bulk edit when you do not want to open a full editor or upload the document.
Renaming a product term across a FAQ, fixing a repeated typo, or swapping a placeholder like {{NAME}} are common jobs. Literal matching keeps behavior predictable — this page is not a regex workbench.
Paste text, enter Find and Replace values, and apply. Replace-all is case-sensitive string matching unless the UI states otherwise — check a sample match first. Very large documents can slow the tab during bulk replace.
Replacing a short token can hit insides of longer words (cat inside catalog) — use word boundaries in a regex tool if you need that safety. Smart quotes from Word will not match straight quotes. There is no multi-step undo beyond your clipboard history.
Use it for boilerplate swaps, URL updates in drafts, and placeholder fills. Keep a copy of the original paste until you verify the output.
Frequently asked questions
Different tools use different definitions and parsers, so small gaps are common. Find and Replace applies JavaScript string methods and RegExp in your browser tab with one consistent browser-side rule set. Hidden characters, stricter syntax, or a different tokenizer usually explain the mismatch. Reduce the input to a minimal sample, then add pieces back until the difference appears. Match the rule your destination actually enforces.
Treat the error as a signal that this environment is stricter or configured differently. Browser APIs reject malformed structures early instead of guessing. Convert to a boring intermediate when it helps—plain UTF-8 text, PNG, WAV, or an unlocked PDF—then retry. If the intermediate works, the original encoding was the problem. Keep that minimal sample for the next regression check.
Runtimes disagree even when feature names match. Locales, parser strictness, codec builds, and library versions differ between your browser and CI. Export the exact bytes from Find and Replace, hash them, and compare in the pipeline. Align normalization steps so both systems see the same input. Use the browser result as a reference artifact, then make CI match it.
Desktop apps win on deep feature sets, batch farms, and specialized hardware paths. Find and Replace wins on zero install, private local processing, and speed for the everyday job on this page. Choose desktop software for multi-hour editorial work or exotic edge formats. Choose this tool when you need a correct result quickly without uploading. Many people do a quick pass here first, then open the heavy suite only if an edge case demands it.
Prefer Find and Replace whenever the input is personal, unpublished, customer-owned, or under NDA, because the core transform stays in your browser via JavaScript string methods and RegExp in your browser tab. Cloud services can still help for formats your browser truly cannot decode, but you must trust their retention policy. Strip secrets before any upload. Privacy is usually the reason to stay local—not a longer marketing checklist.
Start from the best original input you still have. Change only what the destination requires. Prefer lossless intermediates when you must convert twice. Because the tool is local, iterate in small steps: tweak one setting, re-run, compare. Spot-check a short sample before batching anything important.
No account is required for normal use. The core find replace transform runs in your browser on your device using JavaScript string methods and RegExp in your browser tab. You get on-screen output, a copy action, or a download without a mandatory ToolBrigade upload for that step. Keep your browser updated. A few lookup utilities may call public reference APIs for live fields only—they still do not need your private documents.
Lighter text, code, calculator, and many image jobs work on modern phones. Large video encodes and huge PDFs are happier on a plugged-in laptop with more RAM. Fully client-side flows can continue offline once scripts are cached; live lookups still need network. If a run seems stuck, try a smaller sample, free memory by closing tabs, and confirm the input is not truncated. Prove the path on a short fixture before blaming the algorithm.
