02 / what you get
What happens to your data
Kept
- The first row is used as the header and empty lines are skipped
- Quoted cells that contain tabs, quotes or line breaks are read correctly
- A clean Excel workbook with one sheet, where plain numbers are real numeric cells you can sum and sort
- Values like 007 or phone numbers stay text, so leading zeros are not lost
Good to know
- Values arrive as text and become numbers only where that is unambiguous and the target can hold numbers.
- The result is plain values on one sheet named Sheet1. There are no formulas, styles, column widths or charts.
- Dates stay as text, they are not converted to Excel date cells.

TSV vs XLSX
TSV
A TSV (Tab-Separated Values) file is just like CSV, but it uses tabs instead of commas to separate columns. It's handy when the data itself contains commas — like addresses or descriptions — since tabs won't get confused with the content.
Used in: Spreadsheet exports · Data containing commas · Bioinformatics data
XLSX
An XLSX file is a modern Excel workbook: sheets of cells with numbers, text, formulas and formatting. It is the default for spreadsheets today. Converting it gives you the first sheet as plain data (JSON keeps every sheet), so other tools can read it.
Used in: Excel · Business reports · Financial data
