I will clean your excel or CSV data and deliver an auditable report
About this Gig
Turn a messy order table into clean data you can check.
I normalize agreed date formats, amounts and labels, remove exact duplicates under your confirmed unique key, and separate invalid or conflicting records. Missing amounts are never replaced with zero. Conflicting IDs stay out of totals until confirmed.
Basic: 1 file, up to 100 rows / 10 columns; cleaned CSV, exclusions, change log and offline HTML report.
Standard: up to 1,000 rows / 20 columns; Basic outputs plus an Excel report and 2 group summaries.
Premium: up to 10,000 rows / 30 columns; Standard outputs plus a reusable Python script, rules and instructions for one fixed schema.
Send a redacted 20-50 row sample before ordering. We must agree the unique key, dates, currency, refund handling and expected output. One correction to agreed rules is included.
AI-assisted coding and automated tests are used. Portfolio data is synthetic. Structured values only; no OCR, macros, legacy XLS or multi-currency conversion. Do not send passwords or authentication codes.
FAQ
What do you need before I order?
Send a redacted 20-50 row sample. Confirm the unique key, required fields, date formats, currency, refund handling, expected report and deadline. Confirm whether a row means an order or an order line before deduplication.
What happens to invalid or conflicting rows?
They are kept in a separate file with original values, source record numbers and reasons. Conflicting records under the same key are excluded as a group. Missing amounts are not zero-filled, and ambiguous dates are not guessed. Confirm corrections before rerunning.
Do you use AI, and which file types are supported?
Yes. This service uses AI-assisted coding and automated tests. The portfolio uses synthetic data. CSV and one XLSX worksheet of structured values are supported. Formula sheets must be exported as values. OCR, macros, legacy XLS and multi-currency conversion are not included.
