Frequently Asked Questions

Everything you need to know about our string sorting tool.

Do I risk exposing my sensitive data uploading it?

No. All data processing occurs locally directly in your web browser. Nothing gets sent external via the internet ensuring 100% data privacy.

How does the Case Sensitive function work?

When 'Case Sensitive' is ticked, 'Apple' and 'apple' remain as two different lines. If removed, the tool will treat them identically and erase whichever replica arrives later down the list.

Can I deduplicate rows on long CSV datasets?

Yes, providing your CSV operates accurately line-by-line. If identical rows match up absolutely perfectly character-by-character, it'll effortlessly deduplicate and pull out the repetitive entries.

What does 'Trim Whitespaces' actually fix?

It deletes any spaces or tab keys hiding at the extreme start or end of your text snippet. These invisible characters commonly interrupt sorting workflows or register as fake duplicates.

What capacity limitations am I restricted by?

Since logic runs inside your Local PC's memory constraints, text parsing limits stretch to roughly five million rows depending on your CPU/RAM. Browser bounds dictate the exact limit, not server timeouts.

Privacy-First Tool

Your data never leaves your browser. Everything happens in your browser. No uploads needed. Ensuring complete privacy and security. No registration, no data collection, no server uploads.
