Frequently Asked Questions

Can it auto-detect the delimiter?

Yes. With "Auto-detect" selected, the tool counts commas, semicolons, tabs, and pipes in the first line and picks whichever appears most. You can override manually if the detection is wrong.

Does it handle quoted fields with commas?

Yes. RFC 4180 style — values wrapped in double quotes can contain the delimiter, newlines, and escaped quotes (""). The tool's parser handles these correctly.

Are numbers preserved as numbers?

Yes. Plain numeric strings get written as numeric cells in the XLSX, so Excel formulas (SUM, AVERAGE, etc.) work straight away. Leading zeros and IDs that look numeric stay as strings if you wrap them in quotes in the CSV.
