Frequently Asked Questions
What is "auto" sort type?
Auto detects whether the column values look like numbers and applies numeric sorting if so, otherwise falls back to text sorting.
Is the header row sorted too?
No. The first row is always kept at the top and is not included in the sort.
Can I sort by multiple columns?
Currently only single-column sorting is supported. For multi-column sorting, import your CSV into a spreadsheet.
Does it handle CSV with quoted fields?
Yes, quoted fields containing commas are parsed correctly before sorting.
