XLSX vs CSV
XLSX
XLSX is the modern Excel spreadsheet format. It stores worksheets, values and formatting in a compact, structured package.
CSV
CSV stores table data as plain text with values separated by commas. Almost every spreadsheet, database and analytics tool can read it.
Does converting affect quality?
Values from the first sheet of your workbook are written as plain text, with formulas replaced by their calculated values.
Frequently asked questions
Are my files uploaded to a server?
No. This converter runs entirely in your browser, so your files never leave your device.
Which sheet is converted?
The first sheet in your workbook. Move the sheet you need to the front before converting.
What happens to formulas?
The calculated values are written into the CSV, not the formulas themselves.
