I will validate sales CSV files and create a python report
About this Gig
Need reliable CSV files before reporting? I validate and clean sales CSVs with a repeatable Python workflow, then deliver a cleaned output and clear findings. Basic ($25): validate one CSV, flag missing fields, duplicates and schema issues, and return a cleaned file. Standard ($65): process up to three compatible CSVs, consolidate them, provide a validation summary and Python source. Premium ($125): process up to five compatible CSVs and add a KPI HTML report and Python source. Checks can cover required columns, data types, missing values, duplicates, date and amount formats, and sales breakdowns. Row counts or totals are compared only when you provide expected values or a trusted reference; otherwise I report observed values without calling them reconciled. Before ordering, share a sample CSV, desired output columns, cleanup rules, and expected totals if available. Please remove personal and payment details. Packages cover file-based CSVs with compatible headers; live APIs, databases, scheduled pipelines, and financial audits are excluded.

FAQ
Can you work with CSV files that have different columns?
Please share a sample from each file first. The packages require compatible structures; major schema changes may need a custom scope.
What do you need from me to get started?
Please provide the CSV file or a sanitized sample, required output columns, cleanup rules, and any expected row counts or totals you want checked. Please remove personal, payment, or confidential details.
Can you verify whether totals are complete and correct?
I can compare observed row counts or sales totals with expected values you provide. Without an independent expected total or reference, I report the observed results and flag anomalies, but I cannot certify completeness.
Do you connect to APIs, databases, or live systems?
The listed packages are for file-based CSV processing. Live API or database integrations and scheduled pipelines are not included; those would need a separate scope and technical review.
