    What does merging Excel files mean?

    Merging Excel files means putting the content of two or more workbooks (.xlsx, .xls, .ods or .csv) into a single file. It is what you need when you receive the same report from several branches, people or months and want to work with everything in one place.

    There are two ways to do it: copy each sheet as a tab of the new workbook, keeping its formatting, or stack the rows of every file one below the other to consolidate the data in a single table.

    Advantages

    • Save time: no more copying and pasting sheet by sheet.
    • Keeps fonts, colors, borders, number formats and column widths.
    • Aligns columns by header name even when they are in a different order.
    • Accepts XLSX, XLS, XLSM, ODS and CSV, and downloads as XLSX, XLS, ODS or CSV.
    • Private: files are processed in your browser.

    How to merge Excel files

    1. Drag your files onto the tool or click to choose them. You can add several at once.
    2. Put them in the order you want in the result and remove the ones you do not need.
    3. Choose the mode: "one tab per sheet" or "stack rows in a single sheet".
    4. Adjust the options (headers, source column, empty rows) and the output format.
    5. Click the button to merge and download the new file.

    Ideas for using it

    • Merge the sales reports of several branches.
    • Consolidate expenses or attendance for every month of the year.
    • Combine form responses exported to several files.
    • Bring together customer or product lists from different teams.
    • Prepare a single file for a pivot table or a report.

    Tips for the best result

    • To stack rows, use the same header names in every file.
    • Turn on the source file column to know where each row comes from.
    • If you only care about the data, convert formulas to values.
    • Download as XLSX to keep as much formatting as possible.

    Frequently asked questions

    Is it free to merge Excel files?

    Yes. You can merge as many files as you like, with no sign-up and no watermarks.

    Are my files uploaded to a server?

    No. The files are read and merged inside your browser, so they never leave your device.

    Can I merge files in different formats?

    Yes. You can mix XLSX, XLS, XLSM, ODS and CSV in the same merge.

    What if the columns are in a different order?

    In stack mode you can align columns by header name, so each value lands in the right column even when the order changes between files.
