About CSV files
CSV, short for comma-separated values, is the simplest way to store a table: plain text, one row per line, with commas or semicolons between the values. Almost every spreadsheet, database, online shop and mailing tool can import and export it.
That simplicity has a price: no formatting, no sheets, and Excel sometimes mangles numbers and dates when it opens a CSV directly. These converters turn CSV into a proper Excel workbook or JSON, and back again.
