Common Scenarios
Update repeated URLs, domains, tags, or variable names in copied text.
Apply multiple cleanup rules to template exports or CMS snippets.
Use regex groups when repeated formats need captured values.
Replacement Rules
Rules run from top to bottom, so later rules see earlier replacements.
Plain mode treats the find side literally.
Regex mode treats the find side as a JavaScript regular expression and supports $1-style groups.
Usage Advice
Put narrow rules before broad rules to avoid replacing text too early.
Test regex rules on a small sample before processing large text.
Turn off case sensitivity when copied text uses inconsistent capitalization.
Limitations & Compatibility
This is not a CSV parser, HTML sanitizer, or code refactoring engine.
Invalid regex rules stop processing and keep the original input unchanged.
Browser text limits apply; process huge exports in chunks.
Privacy & Security
Processing happens locally in your browser. Input and rules can be kept as local drafts; generated output is not synced or uploaded by this tool.
