Yes.  Each file's data will be joined vertically (top to bottom). You will be able to rearrange the Excel files in the application window prior to merging.

If you are merging .xls files, the maximum row count allowed per file is 65,536. If your merged file needs to exceed that, you will need to use the .xlsx file format, where the maximum row count can be close to 1 million. Bulk File Merger does not restrict file sizes.

For Excel files, data in each row is inserted below each other and this is done for all selected files. Files are combined according to the order in application's window. The same pattern of merging applies to CSV and Text files.

The standard version of Bulk File Merger merges data from each sheet tab, file by file without issues. In the Pro Version, you will be given the choice to include worksheet tabs in the merge.

No, Bulk File Merger will take care of files with different row headings. In fact, you can have any number of columns or rows in each file. Blank spaces and special characters do not affect the file merge. Note: in the Pro version, you can choose to ignore all row 1 data (headers) below the first row and ignore duplicate rows.

Not at all. The cell's values are carried over in the merge but the formula statement will not be available.

If you need multiple licenses, we do offer volume discounts

We do offer our license owners 3 free license key resets in order to move keys around, for situations shown above. Visit the reset page.

In the example above, you can reset the key so that the home desktop computer can be activated, while the laptop will go into limited/demo mode. If you need to have both laptop and desktop fully activated, you will need one additional key.
