How it works

1

Upload your Excel file

Select an XLSX or XLS file. The first sheet of the workbook will be used for the export.

3

CSV is generated with UTF-8 encoding

All values are written to a comma-separated file with UTF-8 encoding, compatible with any tool that accepts CSV.

4

Download and use in your pipeline

About Excel (XLSX) to CSV

Excel spreadsheets are the standard format for sharing data between people, but they are unsuitable for programmatic processing: databases, APIs, ETL pipelines, and data import tools almost universally expect CSV. Converting an XLSX to CSV strips formatting, merged cells, and formula syntax while preserving the underlying data values in a universally compatible plain-text format. This converter exports the first sheet of the uploaded file as a UTF-8 encoded CSV with rows and column headers intact. It is used by eng...

→ Convert an Excel product list to CSV before importing it into a CMS, PIM, or e-commerce platform. → Export a spreadsheet to CSV before loading it into a pandas DataFrame or analysis script. → Convert an Excel report to CSV before ingesting it into a database or data warehouse pipeline. → Prepare a manually maintained Excel config file as CSV for use in an application config loader.

❓ Frequently asked questions 4 answers

Only the first sheet is exported. If you need a different sheet, open the file and move your target sheet to the first position before uploading.

No. The CSV receives the calculated result of each formula cell as a plain value, not the formula itself. This is correct for data interchange — CSV does not support formulas.

Merged cells are resolved to their displayed value. The top-left cell of a merged region receives the value; all other cells in the merged region are exported as empty strings.

The output uses UTF-8 encoding with a BOM header so it opens correctly in Excel on Windows as well as in Linux and macOS command-line tools.
