About this tool

About this tool

Excel to CSV transforms an XLSX or XLS sheet into delimited text by reading workbook data in the browser and outputting rows with proper quoting. You select the sheet and delimiter before conversion.

Read an Excel worksheet and export its rows as clean CSV. Use the full-width workspace to clean and normalize content while reviewing rows, columns, headers, delimiters, and values. The tool accepts Excel and XLS, provides focused options, and creates CSV output that you can inspect, copy, download, or save as a local draft.

Built for daily work

  • Use Excel to CSV Converter for data imports, spreadsheet cleanup, reporting, and database preparation.
  • Remove routine quality problems while preserving useful data before content is imported, published, committed, shared, or passed to another application.
  • Check a small sample interactively before applying the same operation to a larger tabular data workflow.
  • Prepare cleaner CSV output for teammates, clients, documentation, testing, or downstream automation.

Key features

Key features

XLSX and XLS file support

Open Excel workbooks in both the newer XLSX format and the legacy XLS format, reading cell values from the first worksheet and converting them to CSV.

Formula results extracted as values

The tool extracts the calculated values from formula cells rather than the formula text itself, so your CSV contains the numbers and text that Excel would display.

Select which worksheet to convert

For workbooks with multiple sheets, choose the specific worksheet whose data you want to export as CSV.

Cell values rendered as text

Dates, currencies, and percentages are converted to readable text representations in the CSV output, avoiding raw numeric serial values that require re-interpretation.

Convert an Excel file to CSV without breaking the data

CSV is the universal import format, but Excel exports often corrupt accents, strip leading zeros, and guess date formats. The [Excel to CSV converter](tool:excel-to-csv) converts locally with explicit encoding and delimiter choices, and the [UTF-8 guide](guide:excel-to-csv-utf8) covers the pitfalls in detail.
