This is a simple workflow snippet that can be used to merge the data of multiple Excel files which reside in different folders within a specified parent folder. You can simply add this workflow to your solution and pass the parent folder path so that it will simply do the search and provide the merged data as an output.

Once you provide the parent folder path, the workflow will first find all the sub-directories within the specified parent folder. Each sub-directory folder will be then looped to search for .xlsx files within the folders. All the found Excel files will be then added to a List<string> which will be used later to extract data.

This list will be then looped to access each Excel file. Within the loop, the workflow uses an Excel application scope to find all the available workbook sheets within the Excel file. If there are multiple sheets, the data in all the sheets will be extracted onto a data table variable. However, if you wish to extract data only in a specific sheet, please remove the loop that is used to loop through the workbook sheets. Additionally, make sure to provide the sheet name in the Read Range activity since it will not be capturing the sheet name if the loop is removed.

The extracted data will be stored in a temporary data table variable and will be merged into another data table outside the loop. This second data table variable will actually hold all the data that are extracted from each file and finally it will be assigned to a output parameter to return the data.

Input argument - In_FolderPath - provide the parent folder path

Out argument - Out_MergedData - returns the merged data of all processed Excel files

If column names are different then will it merge Horizantally or Vertically ?

I have two workbooks. The first one contains 9 sheets and the second one only one sheet. My output file only capture data of the last sheet on the first workbook + the content of the second workbook, which only contains one sheet. Can you please help me to figure out the reason why the 8 remaining sheets (1 to 8) are not being processed? Thanks.

Is possible to merge the content of the cells on the same column (only one excel file) that are equals?

Tried it - Simple - tried it. it works.
One thing that could be improved would be the checking for null values and dealing with merging conflicts. Maybe some options for the merge could be added!


Great! Its works  - Nice work...try it improve !
