Yes that is possible but you need Python for that > [@write data to excel sheet on row 10](https://forum.knime.com/t/write-data-to-excel-sheet-on-row-10/12897/6): > > well … there is a way. You could use the Python module [openpyxl](https://openpyxl.readthedocs.io/en/stable/) and open the stored excel file in Python and do some manipulations and then save it again. Openpyxl offers a wide range of possibilities. Please be aware that this might not be the most stable way, and it could get tricky if you have large or complicated Excel files.

And also one from the example from before. I think you have to provide the Python Script with a valid path (in this case I used the path of the workflow) and you have to close the file at the end.
