Difference from Excel to CSV

Sheets, Delimiters, Formulas, and Formatting Notes

Multi-sheet workbooks let you pick and export one worksheet at a time.
CSV stores one table at a time.
Comma is the most common delimiter.
TSV uses real tab characters between values.
Formatting, colors, charts, comments, macros, and merged cells are not part of standard CSV.
Dates read as YYYY-MM-DD; leading zeros and long IDs may need care in spreadsheet apps.
