Find and Replace Text lets you enter exact-match words, then swap them across a whole block. It saves serious time when you edit large text from a single pattern.
Find and Replace Text finds exact match words and swaps them across a text block you paste in. It helps a lot when you’re editing large text because it hits every occurrence in one pass. You set the old string once, pick the new one, and the tool rewrites the whole block for you.
How Do You Get Started?
When Should You Match Case?
Match Case is case sensitive, so “a” does not match “A” during the swap. Turn it on when capital letters matter and you don’t want lower ones touched by mistake.
Example:
- Input: Text and Replace Text Online!
- Find: r
- Replace: Y
- Result: Text and Replace Text Online!
- Replaced: 0
What Whole Words Mode Does
Whole Words only replaces a word that isn’t preceded or followed by another string. Partial pieces inside longer words stay untouched, which keeps edits clean when fragments share letters.
Example: Input “The quick brown fox jumps over the lazy dog.” Find “brow” Replace “eyebrow” leaves the line unchanged with Replaced: 0, since brow sits inside brown.
Which Files Can You Open?
You can open plain text files from your device when you don’t want to paste by hand. Rich text from editors should go straight into the box instead, since the reader sticks to simple formats only.
How Regular Expressions Work
Regex lets you run complex searches beyond plain words when a simple string isn’t enough. Escape specials with a backslash or you’ll get a SyntaxError about an invalid regular expression. characterconverter.com keeps these patterns easy to try without leaving the page.
Why Nothing Leaves Your Browser
The tool works locally in your browser, so no data is uploaded to the server at all. You still get file upload, Match case, Whole words, regex, and Save as under file options. That local setup is why people trust a find and replace text pass on private drafts without worry.
What People Usually Ask
Does It Replace Every Match?
Yes. The tool is greedy and replaces all occurrences of the fragment you enter in Find this with whatever you put in Replace with. One click covers the full block so you don't chase leftovers by hand.
Can I Upload a Document?
Yes. Use Open File to upload plain types like .txt, .html/.htm, .css, .js, .bat, .nfo, and .md. For rich text from an editor, paste the content into the box instead of uploading.
Is Match Case Required?
No. Match Case is optional and only needed when you want exact case so “a” will not match “A”. Leave it off for broader swaps, or flip it on when capital letters must stay precise.
Do Whole Words Stop Partial Hits?
Yes. Whole Words only replaces the exact word when it isn't joined to other characters. Finding brow inside brown leaves that word unchanged, so partial hits don't sneak into longer terms.
Is My Text Sent to a Server?
No. Everything runs locally in your browser and no data is uploaded to the server. Your draft stays on your machine for the whole find and replace text run, which keeps private notes private.
How Do I Save the Result?
Copy the output after Replace, or pick Save as under the file menu when you want a file on disk. Both paths sit right in the tool, and the latest flow on characterconverter.com still uses that same simple file menu.
