Questions & answers

Which duplicate spelling is kept?

The first matching line stays. Later matching lines are removed. Trimming and case settings affect the match.

Can I remove duplicates without sorting?

Yes. Choose Keep original order with duplicate removal enabled.

What is natural sorting?

Number sequences are compared numerically, so item2 appears before item10.

Does it sort every language alphabet correctly?

Sorting uses English browser collation. Language-specific order may differ; use the original-order option when order must be preserved.

Why are exports longer than the preview table?

The table displays at most 200 rows to keep the page responsive. TXT and JSON include the complete result.

Can I save the result?

Yes. Download the text result or JSON report, or copy the result. Editing inputs invalidates the previous result until you calculate again.

Is my input uploaded for processing?

Processing runs in a local browser worker with no input upload and no account. Website advertising and analytics are described in the privacy information.
