Spreadsheets tips

πŸ“Š

Download the converted CSV and drag it into Excel or Google Sheets β€” it will auto-parse columns. No copy-paste needed.

πŸ’‘

Commas in values are automatically quoted: "New York, NY" becomes "New York, NY" in the CSV so spreadsheets parse it correctly.

πŸ“‹

For Google Sheets: convert here, copy the CSV output, and use File β†’ Import β†’ Paste to import without saving a file first.

πŸ”’

Numbers remain as numbers in the CSV (no quotes). Spreadsheet apps will recognise and format them as numeric cells automatically.
