How to use Convert Excel to CSV
- 1. Add your workbook. Drop an .xlsx file, or browse to choose one, into the file picker. The workbook is read directly in your browser, so its contents are never uploaded anywhere.
- 2. Pick the sheet to extract. Enter the Sheet number for workbooks with multiple tabs. Sheet 1 is the first tab by default; change it if the data you need lives on a later sheet.
- 3. Copy the CSV output. Copy the plain comma-separated rows generated from the chosen sheet and paste them into a text file, a script, or any tool that expects CSV rather than a binary workbook.
When to use Convert Excel to CSV
Convert Excel to CSV extracts one sheet from an .xlsx workbook and turns it into plain comma-separated rows, without needing Excel installed. Reach for it whenever a script, database or import form only accepts CSV but your source data lives in a spreadsheet.
- Feeding a spreadsheet into a script. A data pipeline or Python script expects CSV input, but the source of truth is an Excel workbook someone maintains manually. Converting the relevant sheet keeps the pipeline running.
- Importing into a database or CRM. Many bulk import tools only accept CSV files, not Excel workbooks. Extracting the sheet with your contact list or inventory as CSV clears the way for a clean import.
- Extracting one tab from a multi-sheet report. A shared workbook has separate tabs per month or region. Setting the sheet number lets you pull out just the tab you need without opening Excel to copy it manually.
