So I have a project I'm working on where I have a large excel spreadsheet and I want to search one of the columns/cells and if the cell contains a certain word then I want to add a tag in another column but the same row.
So the cell would have a long description in it and if the description contained a keyword I'm looking for it would add a tag in another column in the same row. I would like to able to search for more than one keyword at a time.
I've messed around with openpyxl for awhile but that hasn't really panned out. I am familiar with python, C, C++, and Java so if you could help me with any of those languages I would really appreciate it. Python is preferred.

pandaslibrary in Python. It has some useful functions to help search through a dataframe. You can also read in excel sheets as dataframes.
