Make one small spreadsheet easier to use, while keeping every change traceable.

Best fit: one non-sensitive CSV or values-only XLSX table, up to 500 rows and 15 columns. I handle agreed whitespace and formatting rules, exact duplicates, and flags for missing or conflicting values. Identifiers stay intact, including leading zeros; uncertain values stay visible for your decision.

You receive the unchanged original, cleaned XLSX, a change log and an exception list. CSV is included when appropriate, with import guidance where text identifiers need protection. Checks cover row counts, approved exclusions, IDs, meaningful zeros and unresolved entries.

Start with a description: file type, row and column counts, the intended use, duplicate rules and date/number conventions. Please do not attach sensitive records. Once fit is confirmed, files and delivery stay in the private Contra project.

US$30/hour. Before payment, we agree the exact rules, estimated hours, a maximum charge and a delivery date based on capacity. No extra hours without approval. Plan for at least five business days after complete inputs and verified funding; the actual date is confirmed in writing. One correction within the agreed scope is included when requested within seven calendar days of delivery.
