Frequently Asked Questions

Quick answers for CSV Sorter users

Can I sort by multiple columns?

Yes, add multiple sort rules with different columns and directions. Rows are sorted by the first rule, then ties are broken by subsequent rules.

Does it handle numeric sorting correctly?

Yes, the sorter detects numeric columns and sorts them as numbers (1, 2, 10, 20) instead of alphabetically (1, 10, 2, 20).

Is there a row limit?

No hard limit. The tool processes data in your browser, so performance depends on your device. Datasets with tens of thousands of rows work smoothly.

Does CSV sorting upload my data?

Sorting runs in your browser for this operation. The selected or pasted CSV is processed locally to reorder rows.

Can I sort dates?

Dates in standard formats (ISO, MM/DD/YYYY) are handled. For best results, ensure consistent date formatting in your CSV.

Does it preserve the original data?

Yes, sorting only changes row order. No data values are modified. Download the sorted version as a new file.

Why does my sorted CSV look different in Excel or Sheets?

Spreadsheet apps may reinterpret dates, long numbers, leading zeros, or quoted fields when opening CSV files. Check formatting after import if your file contains IDs or date columns.

Can I download the sorted CSV?

Yes, after sorting you can download the result as a clean CSV file or copy it to your clipboard for immediate use in other applications.
