Expert Q&A
Does this support escape sequences like \n or \t?
Yes! When "Use Regex" is enabled, you can use all standard regular expression escape sequences, including newlines (\n), tabs (\t), and more complex patterns.
What is "Whole Word Match"?
If you search for "cat" with whole word match, it will ignore "caterpillar" or "concatenate". It only replaces the exact word "cat" surrounded by boundaries like spaces or punctuation.
How many files can I process at once?
Technically, there is no hard limit on the number of files. The tool is optimized to process files sequentially to manage memory. Large individual files (over 50MB) may slow down your browser slightly during processing.
