Find & Replace
Find and replace text, with regex support.
How to use it
- Paste your text into the main text area.
- Type the text you want to find in the "Find" field.
- Type the replacement text in the "Replace with" field (leave blank to delete matches).
- Toggle options like case sensitivity or regex mode, then click "Replace all."
Examples and use cases
Bulk renaming in content
A product name changed across 50 pages of documentation. Find the old name and replace it with the new one in your pasted text.
Cleaning up formatting
Replace double spaces with single spaces, or swap tabs for spaces throughout a document.
Regex-powered transformations
Use regular expressions to restructure text — reformat dates, swap name order (last, first to first last), or extract patterns.
Stripping unwanted content
Find a pattern and replace it with nothing to strip tags, markers, or repeated phrases from pasted text.
CSV and data cleanup
Replace delimiters, standardize formatting in data fields, or fix inconsistent values across rows.
Frequently asked questions
- What is regex?
- Regex (regular expressions) is a pattern language for matching text. It lets you search for patterns instead of exact strings. For example, \d+ matches any sequence of digits, and [A-Z] matches any uppercase letter.
- Do I need to know regex to use this tool?
- No. With regex mode off, the tool works as a simple text find and replace. Regex mode is optional for users who need pattern-based matching.
- What does "case sensitive" mean?
- When case sensitive is on, "Hello" only matches "Hello" — not "hello" or "HELLO." When off, it matches all case variations.
- Can I use capture groups in regex mode?
- Yes. Use parentheses to capture groups in the find pattern, then reference them with $1, $2, etc. in the replacement. For example, find (\w+)\s(\w+) and replace with $2 $1 to swap two words.
- Is my text sent to a server?
- No. All find-and-replace processing runs in your browser using JavaScript. Your text never leaves your device.
- What happens if my regex is invalid?
- The tool shows a clear error message explaining what went wrong in your regex pattern. Your text is not modified until you fix the pattern.
- Is there a text length limit?
- No hard limit. The tool handles large texts comfortably since everything runs locally in your browser.

About this tool
Find and replace is one of the most fundamental text operations. Every text editor has it, but sometimes you need to run a quick replacement on text that is not in an editor — pasted from a website, exported from a spreadsheet, or copied from an email thread.
The Wordshed find and replace tool adds regex support for users who need pattern-based transformations. It shows a live match count so you can verify your pattern before replacing, and highlights matches in the text so you can see exactly what will change. Everything runs in your browser.
