About this Gig

I will clean a small Excel or CSV table using rules we agree on before processing.


This service includes trimming unwanted spaces, standardizing agreed date and number formats, removing fully identical records when authorized, and identifying missing or conflicting values.


You receive a cleaned XLSX, a CSV copy, an exception list and a row-by-row audit. IDs are kept as text. Ambiguous dates, missing information and conflicting IDs are flagged for your decision instead of guessed.


The basic package covers one plain-data CSV or single-sheet XLSX, up to 100 data rows (one row per item), 10 columns and 5 MB. One revision within the agreed scope is included. Please contact me before ordering if your file contains formulas, macros, multiple sheets, sensitive information or requirements outside this scope.


I use local rule-based tools. AI may assist with scripting using synthetic examples; your source files are not uploaded to an AI service without your explicit authorization. I remain responsible for checking the delivery.


The portfolio shown is a self-initiated demonstration using synthetic data, not a past client order.
