Excel to CSV Converter
Open an Excel workbook and pull a single sheet out as a clean CSV file. Pick the sheet, choose a comma, semicolon or tab delimiter, and download a plain-text file any tool can read.
An Excel to CSV converter pulls one sheet out of a workbook as a plain-text CSV that any tool can read. Open your XLSX or XLS, pick the sheet, choose a comma, semicolon or tab delimiter, and download the file, so it works to convert XLSX to CSV or export a single tab for an import. Dates and numbers are written as clean values, and cells that contain a comma are quoted so the columns never break. The workbook is read on your own device and is never uploaded.

Frequently asked questions
- My Excel file has several sheets: can I convert one?
- Yes. Every sheet in the workbook is listed, and you pick exactly which one to export. CSV holds a single table, so you convert one sheet at a time, which keeps each output clean and predictable.
- Which delimiter should I choose?
- A comma is the default and works almost everywhere. Choose a semicolon if your data already contains commas or you will open the file where Excel expects semicolons, and tab if a tool asks for TSV. A cell such as Smith, John is wrapped in quotes as "Smith, John" so the comma inside it never splits the columns.
- Will dates and numbers stay correct?
- Yes. Numbers are written as plain values and dates are written in a standard text form, so the CSV reads cleanly in spreadsheets, databases and scripts without the formatting quirks Excel sometimes adds.
