About Excel to CSV

Excel to CSV converts .xlsx and .xls spreadsheet files locally in your browser and exports the selected worksheet as CSV text. Files are not uploaded, so it is suitable for business data, import templates, and report tables.

Key Features

  • Local conversion: Excel files are parsed in the browser.
  • Worksheet selection: Detect all worksheets and export the selected sheet.
  • Delimiter options: Use comma, semicolon, or Tab for different import systems.
  • Single CSV download: Export the current worksheet as UTF-8 CSV with BOM.
  • Batch export: Package all worksheets into a ZIP, with one CSV per worksheet.

How To Use

  1. Click the upload area or drop an Excel file.
  2. Choose the worksheet to convert.
  3. Select the delimiter required by your target system.
  4. Download the current CSV or export all worksheets as ZIP.

Use Cases

  • Import Excel reports into databases, ERP, CRM, or BI systems.
  • Split multi-sheet workbooks into separate CSV files.
  • Convert XLSX/XLS files into a plain-text data format.
  • Prepare CSV files for data cleaning, scripts, and batch imports.

Notes

  • CSV keeps cell text and values only. It does not preserve formulas, colors, merged cells, charts, or Excel styling.
  • Large files depend on browser performance and available memory.
  • If a target system requires special encoding or column formatting, process the downloaded CSV with a dedicated tool.
