Replace Rules
Frequently Asked Questions
Q: Can I apply multiple rules at once?
Yes, you can set up multiple rules for bulk replacement. Use the checkbox for each rule to enable or disable it individually. Rules are applied in order from top to bottom.
Q: How do I use regular expressions?
Check "Use Regular Expressions" to use regex patterns in search strings. For example: "\d+" matches consecutive digits, "\s+" matches whitespace characters, "^" matches the beginning of a line, and "$" matches the end of a line.
Q: When should I use the Smart Quotes preset?
Use this preset when you have text with curly quotes, typographic quotes, or various international quotation marks that need to be standardized to straight quotes. This is useful for code formatting or when preparing text for systems that don't support special characters.
Q: Can I customize preset contents?
When you click a preset button, predefined rules are loaded. After loading, you can freely edit, add, or delete rules to create your own custom ruleset based on the preset.
Q: Can it handle large files?
All processing happens in your browser, so files up to several MB work fine. For very large files, processing may take a moment but will complete without issues.
Q: Is replacement history saved?
The current version doesn't save replacement history. We recommend backing up important text before making significant changes.
