About this tool
About this tool
Find Replace updates text by searching for a literal string or pattern and substituting a replacement across the entire document inside your browser. Case sensitivity and whole word options control matching behavior.
Replace matching text with optional case and regular expression controls. Use the full-width workspace to process content while reviewing lines, words, characters, whitespace, and Unicode content. The tool accepts plain text, provides focused options, and creates plain text output that you can inspect, copy, download, or save as a local draft.
Built for daily work
- Use Find and Replace for editing, publishing, data preparation, and everyday text cleanup.
- Apply the selected operation and produce a reviewable result before content is imported, published, committed, shared, or passed to another application.
- Check a small sample interactively before applying the same operation to a larger plain text workflow.
- Prepare cleaner plain text output for teammates, clients, documentation, testing, or downstream automation.

Key features
Key features
Plain text and regex search modes
Search for literal strings or use regular expression patterns with capture groups, character classes, and quantifiers for more complex matching.
Case sensitivity toggle
Enable case-sensitive mode to match exact letter casing, or disable it to find all variations of the search term regardless of capitalization.
Replacement with match count
After replacing, the report shows how many matches were found and replaced, so you can confirm the scope of the change before using the output.
Full result preview
The output panel shows the complete text with all replacements applied, letting you scroll through and verify that no unintended substitutions were made.
