What does this tool do?
The Find and Replace tool searches your text and replaces matches online, with case-sensitive and regex options. It shows the number of matches found and safely warns you when an invalid regex is entered. Everything runs in your browser.
How to use it
- Paste your text into the input area.
- Adjust the options to fit your needs.
- Copy the processed text.
Case sensitivity and regex
With the case-sensitive option you can target only exact-case matches or ignore differences in letter case. Turning on regex mode lets you search with patterns, so you can capture numbers, email-like shapes, or repeated spaces and replace them all at once.
Match count and safety
The tool instantly shows how many matches it found, so you can see the scope of the change before applying it. If you type an invalid regex pattern, the app reports the situation safely instead of crashing, and your existing text is preserved.
Frequently asked questions
How does regex support work?
When you enable regex mode, you type a pattern in the search box and the tool interprets it as a JavaScript regular expression; invalid patterns are handled safely and your text stays unchanged.
