Frequently Asked Questions

What is the difference between "All Empty Lines" and "Strictly Empty Lines Only"?

"All Empty Lines" scans and deletes lines that appear blank to the eye but actually contain hidden tabs or spaces. "Strictly Empty Lines Only" preserves lines that contain formatting spaces while removing lines with absolutely zero content.

Will this tool alter the internal indentation of my source code?

By default, the "Trim Whitespace" option will clear out indentation elements at the beginning of lines. If you are cleaning code layouts and want to keep your indentation tabs intact, simply uncheck the "Trim Whitespace from Start/End of Lines" option before running the script.

Is there a hard cap on how much text can be pasted into the input field?

No, there are no software-enforced string length limitations. The tool processes strings directly inside your hardware's local RAM buffer, letting you format massive log registers and data charts smoothly.

How does local client-side processing protect my proprietary company data?

Your inputs never touch external networks or analytics databases. Because the underlying JavaScript runs exclusively inside your local browser tab, your company's data and logs remain fully private and compliant with security protocols.

Does this tool support non-English character scripts or accent configurations?

Yes. The script parses strings natively via modern browser Unicode protocols, making it fully compatible with European accent marks, Asian logographs, special symbols, and standard mathematical characters.
