Find & Replace Tips: Use "Whole Word" to avoid partial matches (e.g., finding "car" won't match "carpet"). Enable "Use Regex" for advanced patterns like \d+ to match numbers or \s+ for whitespace. All processing is secure and stays in your browser.
Why use an Online Find & Replace Tool?
Editing large documents or datasets manually to change a specific word or pattern is tedious and prone to human error.

Frequently Asked Questions
How do I replace multiple different words at once?
Currently, the tool supports one find/replace pattern at a time. However, you can use Regular Expressions with the 'OR' operator (e.g., 'word1|word2') for complex batch finds.
What is 'Whole Word' matching?
When enabled, searching for 'can' will only match the word 'can' and not 'canvas' or 'scan'. This prevents accidental replacements within larger words.
Does the tool support Regex?
Yes! Enable the 'Use Regex' option to use standard JavaScript regular expression patterns for powerful search and transformation.
Is there a limit to document size?
The tool is limited only by your browser's memory. It can typically handle text documents up to several megabytes in size with ease.
Can I use special characters like newlines in Find/Replace?
Yes, by enabling 'Use Regex', you can use '\n' for newlines, '\t' for tabs, and other standard regex escape sequences.
