Merge columns in two spreadsheets

Hi there! My project request is to merge columns in two different spreadsheets. The spreadsheets are in an Excel (.xlsx) format, and there is a common column between the two of them that they can be merged on. The total number of columns for both spreadsheets is less than 10. I'm looking for an experienced professional to handle this project quickly and effectively, within the expected timeline. If you think you have the skills and experience necessary, I'd love to hear from you.
