Update specific excel column of a sheet

I need to update specific column (and cell if possible) of excel sheet once all operations completed into the pipeline.
Read Excel sheet1 → excel parser → mapper → REST POST–> need to update sheet1 column c with status “Completed”

Please suggest which snap will be helpful.

The document contains multiple sheets or just one, and does it have any headers?

document contains multiple sheets (sheet1,sheet2) and also have headers (column1, column2, status).
