Regex (Regular Expression) is a powerful language used to match complex patterns in text rather than just literal strings.

Does this work for multiple occurrences?

Yes, our tool automatically replaces all occurrences that match your 'Find' criteria within the entire text.

How do I use regex in the find-and-replace tool?

Enable the regex toggle, then enter a regular expression pattern in the Find field. For example, \d+ matches any sequence of digits. Use capture groups in the pattern and $1, $2 in the Replace field to insert matched portions into the replacement.

What is the difference between Replace and Replace All?

Replace substitutes only the first occurrence of the search term. Replace All substitutes every occurrence in the text. Use Replace All with regex to make global transformations, such as reformatting all dates in a document at once.

How do I replace line breaks using this tool?

Enable regex mode and use \n to match newline characters in the Find field. For example, to replace every line break with a comma, enter \n in Find and , (comma-space) in Replace, then click Replace All.

Can I save and reuse a set of replacement rules for repeated use?

The Text Replacer currently applies replacements for the current session only — there is no built-in save or rule-export feature. For a repeatable workflow, keep your find-and-replace rule pairs in a text file or spreadsheet and paste them in each session. If you need persistent, scriptable text replacement, command-line tools like sed, awk, or a Python script with re.sub() are more efficient for repeating the same transformations across multiple files or regular automation tasks.

Local processing

Our local file, text and chart tools process content on your device using JavaScript, browser APIs and, where needed, WebAssembly. Our usage events do not include filenames, file contents, input text, chart values, raw errors, emails or license references. Network lookup tools (such as DNS, WHOIS, IP and speed tests) contact external services for their stated purpose. Loading the website, fonts, libraries and models also makes network requests. WebAssembly itself does not prevent network access.
