Frequently Asked Questions
Can I use regular expressions for the replacements?
Yes, enable regex mode for any replacement rule. The tool supports capture groups, lookahead, lookbehind, and all standard JavaScript regex features, making it powerful enough for complex text transformations and code refactoring.
Is there a limit on how many replacement rules I can add?
No limit at all. You can create as many find-and-replace rules as you need. Rules are applied in order from top to bottom, so you can chain replacements and build complex multi-step text transformations.
Can I save my replacement rules for later use?
Since all processing is local in your browser, you can add and remove rules as needed. Each rule can be toggled on or off individually, and you can add new rules at any time to build up the exact set of replacements you need.
Is Batch Replace free, and do I need to sign up or upload my files?
Batch Replace is 100% free to use with no signup, no registration, and no usage limits. All processing happens locally in your browser - your files and data never leave your device, so no upload is required and your privacy is fully protected.
