Frequently Asked Questions
How do I find and replace text online?
Paste your text, type what you want to find and what to replace it with, and the result updates live with matches highlighted. You can replace a single occurrence or all of them at once.
Does it support regular expressions?
Yes. Switch on regex mode to use patterns — for example \d+ to match numbers, or capture groups to reorder text. This lets you perform powerful bulk edits that plain find-and-replace cannot.
Can I make the search case-sensitive?
Yes. There is a case-sensitivity toggle, so "Apple" and "apple" can be treated as the same or as different matches depending on what you need.
Is there a limit on how much text I can process?
No practical limit. Because find-and-replace runs in your browser, you can process large documents quickly and privately without uploading anything.
