Make a small Excel data sheet easier to review and reuse. I will clean ONE .xlsx file containing one plain data worksheet, up to 1,000 data rows and 20 columns. The package includes trimming text, removing agreed exact duplicate rows, highlighting missing cells, and a consistent table layout with filters and a frozen header. You receive the cleaned .xlsx, a short change summary, and one revision within the agreed rules. The original file is preserved. Missing values are flagged rather than invented; text identifiers are kept as text. Message before ordering with a redacted sample, the duplicate rule, the fields that must remain text, and an example of the desired output. Delivery: five days after complete requirements. Formulas, macros, charts, pivot tables, multiple sheets, merged cells, protected files, external links and accounting calculations need separate scope. Existing formatting is replaced with the agreed simple layout. Workbook values and formatting are checked by saving and reopening the file; desktop Excel testing is not included. The example uses fictional records: six rows become four, two exact duplicates are removed and one blank is highlighted. AI-assisted work, checked before delivery; no previous client work is claimed.
