Find and Replace
Renaming a product across a long document, fixing a repeated typo, or restructuring data shouldn't mean editing line by line. Paste your text, see every match highlighted live, and replace them all in one click — with whole-word, case, and full regex support, entirely in your browser.
How to Use Find and Replace
Paste your text
Paste the text you want to edit, then type your search term in the Find box. Matches highlight instantly in the preview with a live count.
Refine the match
Toggle case-sensitive, whole-word, or regex mode until the highlighted matches are exactly what you intend. In regex mode, use $1 to reference capture groups in the replacement.
Replace and copy
Click Replace All. The result appears in the output box with your original untouched — copy it when you're happy.
About Find and Replace
When you need find and replace
Bulk text edits come up constantly: a company renames a product and every mention in the docs must change; a client's name is misspelled forty times in a contract draft; a CSV export uses semicolons where your import needs commas; template placeholders like {{name}} need swapping for real values. Doing these edits by hand is slow and error-prone — you always miss one. A find-and-replace tool with a live match count tells you exactly how many instances exist before you commit, and the highlighted preview lets you verify you're matching the right things, not accidental substrings.
Whole word, case, and regex modes
Three options control what counts as a match. Case-sensitive distinguishes "March" the month from "march" the verb. Whole-word stops "cat" from also matching inside "category" — the classic replace-gone-wrong. Regex mode unlocks pattern matching for edits plain search can't do: find all dates, all email addresses, or all numbers with a unit. Capture groups make regex genuinely powerful — searching for (\d+)px and replacing with $1rem rewrites every pixel value while keeping each number. Invalid patterns show an inline error immediately instead of failing silently, so you can fix the expression before replacing.
How FluidConvert handles it
As you type a search term, every match lights up in the preview panel and the counter updates live — you see precisely what "Replace All" will touch before touching it. The replacement lands in a separate output box, so your original text stays intact in case you want to adjust and retry. Everything runs client-side in your browser: contracts, source code, and customer data are never uploaded or logged. No length limits, no signup. When you're happy with the result, one click copies it to your clipboard.
Common uses for Find and Replace
- Renaming a product, person, or company across an entire document at once
- Converting units in bulk with regex groups, like (\d+)px to $1rem
- Swapping delimiters in exported data, such as semicolons to commas
- Filling template placeholders like {{name}} with real values
- Cleaning scraped or pasted text by removing repeated unwanted phrases
Frequently Asked Questions
What does the whole-word option do?
It requires matches to stand alone as complete words, bounded by spaces, punctuation, or line edges. Searching for "art" with whole-word off also matches inside "start" and "artist"; with it on, only the standalone word "art" matches. This prevents the most common find-and-replace accident — corrupting longer words that happen to contain your search term.
How do I use capture groups in regex mode?
Wrap part of your pattern in parentheses, then reference it in the replacement with $1, $2, and so on. For example, find (\w+)@old-domain\.com and replace with $1@new-domain.com to migrate every email address while keeping each username. The live preview highlights what the pattern matches, so you can confirm the groups capture what you expect before clicking Replace All.
Why does my search show a regex error?
In regex mode, characters like ( ) [ ] + * ? and \ have special meanings, so an unbalanced parenthesis or a trailing backslash makes the pattern invalid — the error appears inline under the Find box. If you meant to search for those characters literally, either escape them with a backslash (\( for a parenthesis) or simply turn regex mode off, which treats every character literally.
Does my text get uploaded when I use this tool?
No. Searching, highlighting, and replacing all run in JavaScript in your browser tab — nothing is transmitted to any server, stored, or logged. That makes it safe for contracts, source code, personal data, and unpublished writing. The tool continues working even if you go offline after loading the page.
Can I undo a replacement?
Your original text is never modified — Replace All writes its result to a separate output box below, leaving the input untouched. If the result isn't right, adjust your search or replacement and click Replace All again; it always re-runs against the original input. Copy the output only when you're satisfied.
