Merge spreadsheets

Several exports, one table

Drop in your XLSX or CSV tables and choose how to put them together: stacked into one sheet, or each as its own sheet in a single workbook. Set the order with the arrows and download the finished workbook.

• Lining columns up by header makes sure Price meets Price even when every export orders its columns differently. A column missing elsewhere is left empty and we point it out.
• A source column records which file each row came from. Without it there is no way to tell afterwards.
• A multi-sheet workbook contributes every sheet separately, nothing is thrown away.

Frequently asked questions

Does the header repeat in the middle of the data?

No. When you tick that the first row is a header, it is taken once and skipped in the other tables.

Are numbers and dates preserved?

Yes. Values are recognised when writing the XLSX, so you can calculate and sort with them straight away.

How many files can it handle?

Up to twenty at 25 MB each. Everything is read in the browser, so with large workbooks expect a moment's wait.

Are the files sent to a server?

No, the merge happens entirely in your browser.
