I will clean, merge and compare excel or CSV spreadsheets

Do you have two spreadsheet versions that do not match, duplicate rows, inconsistent formatting, or a messy CSV that needs to be made usable?

I will clean and structure your Excel or CSV files with a clear, reviewable result:

- remove obvious duplicate rows and normalize spacing and headers

- merge files or split a large file into practical batches

- compare two versions by an ID column or row order

- report added, removed, changed, blank-ID, and duplicate-ID rows

- preserve the original files and return a clean output plus a short change note

I can work with .csv and common .xlsx files. Please send a small, non-sensitive sample before ordering so I can confirm the structure and the right delivery scope. Results depend on the quality and consistency of the source files. This service is data processing, not accounting, legal, compliance, or business advice.
