CSV and Excel Data Cleanup

I offer small-file CSV and Excel data cleanup: removing extra spaces, standardizing agreed formats, and finding duplicates. Deliverables include cleaned files, source-row references, an exception list...
About this Gig

Get one small CSV or Excel table into a consistent, reviewable format.


The starter package covers one CSV or one values-only worksheet, up to 100 rows and 10 columns. I apply agreed rules for whitespace, duplicates, dates and number formats.


You receive:

- A cleaned XLSX and matching CSV

- The original values and source-row references

- An exception list for missing, ambiguous or conflicting data

- A brief change summary


I preserve uncertain values for your decision rather than guessing them. The gallery shows a fictional 18-record demonstration: 16 retained records, two normalized exact duplicates removed, and nine records flagged for review. It is not previous client work.


I use scripts and AI-assisted tools, with outputs checked against the source and agreed rules. Please discuss any AI-use restrictions before ordering and share only authorized, anonymized data.


Please send a representative anonymized sample before ordering. OCR, macros, formula repair, external research and merging multiple files are outside this package.
