Frequently Asked Questions
Does it support regular expressions?
Yes. Enable the regex checkbox to use full JavaScript regular expression patterns, including groups, quantifiers, lookaheads, and character classes.
Can I do case-sensitive replacements?
Yes. Toggle the case-sensitive checkbox to require exact case matching. When unchecked, matching is case-insensitive by default.
Does it support bulk/batch processing?
Yes. Paste any amount of text — the tool processes all matches across the entire content in one operation, handling thousands of replacements instantly.
What are the use cases?
Cleaning up log files, refactoring code variables, normalizing data formats, fixing typos across documents, removing unwanted patterns, and batch-editing CSV or JSON data.
Does it preserve formatting?
Yes. The tool only modifies the matched text and leaves all other formatting, whitespace, and line breaks intact.
Is my data safe?
Absolutely. All processing happens entirely in your browser. No text is sent to any server — your data stays completely private.
