Can I sort the deduplicated lines alphabetically?

Yes. Enabling the "Sort results" checkbox will automatically sort the final unique lines alphabetically (A-Z) after deduplication.

Is there a line limit for the deduplication tool?

No strict limitation is set. The process is executed natively inside your local browser memory, allowing it to easily handle tens of thousands of lines instantly.

Is my input list uploaded to a server?

Absolutely not. All processing occurs within your browser window using secure, sandboxed client-side logic. Your data remains completely private.

Practical Real-World Calculation Examples

Cleaning Email Recipient Lists

Case #1

Scenario: An admin has a disorganized newsletter list with double addresses and leading spacing problems.

Scenario: An SEO consultant wants a clean, alphabetical index of target pages compiled from separate logs.

"/about 
 /services 
 /about" -> Checked Sort results

Result: "/about /services"

Important Notes, Assumptions & Disclaimers

This tool considers lines identical only if they match fully on a character-by-character basis (accounting for casing or spacing settings chosen).
Very large payloads (e.g. over 100MB of raw text) may cause slight rendering lag in older browsers due to UI constraints.

Notice: All calculations occur client-side in browser memory. No data is stored, tracked, or transmitted.
