How to use the Excel Sheet Extractor

  1. Drop an .xlsx or .xls workbook onto the drop area, or click it to browse.
  2. The tool lists every sheet in the workbook. Click the sheet you want. Its row and column count appear underneath.
  3. Click Extract sheet. A preview of the first 200 rows appears below, with the full row and column count.
  4. Pick an output format: CSV, Parquet, JSON, TSV, NDJSON or Excel.
  5. Click Download. The file is named after the sheet, for example Orders.csv. Pick another sheet and repeat to export the rest.

Worked example

A workbook, q3-report.xlsx, has three sheets: Summary, Orders and Returns. You only need the Orders sheet as a CSV file to load into another system.

Input (q3-report.xlsx, Orders sheet)

Sheets found: Summary, Orders, Returns

order_id  customer    amount
1001      Acme Ltd    250
1002      Birch Co    120
1003      Cobalt Inc  75

Settings

  • Sheet: Orders
  • Output format: CSV

Output (Orders.csv)

order_id,customer,amount
1001,Acme Ltd,250
1002,Birch Co,120
1003,Cobalt Inc,75

The first row of the sheet becomes the header. The Summary and Returns sheets are not touched. Select either of them and download again if you need them too.

Frequently Asked Questions

How do I convert just one sheet of an Excel file to CSV?

Load the workbook here, click the sheet name, click Extract sheet and download as CSV. In Excel itself, Save As CSV also saves only the active sheet, so you would have to switch to each sheet and save it separately.

Why do other converters only show my first sheet?

The general Excel converters on this site, such as Excel to CSV, read the first sheet of a workbook. Use this tool when the data you need is on a later sheet.

What happens to formulas?

You get the results, not the formulas. Each cell is exported with the value Excel saved for it. To see the formulas themselves, use the Excel Formula Extractor.

Why do some numbers come out as text?

Cells are read the way Excel displays them. A cell formatted as currency comes through as text like $1,200.00. If you need plain numbers, set those columns to General or Number format in Excel before extracting. Date cells are the exception: they are written as ISO dates such as 2026-03-02, whatever display style the sheet uses.

Is the workbook uploaded?

No. The file is read and converted inside your browser tab. Nothing is sent to a server.
