Useful source files
Sales or order data, an inventory snapshot and product cost information give the application the strongest starting point.
Before you analyse
Check whether your CSV exports are ready.
Upload Sales and Inventory CSVs without logging in. Data Check uses the application’s mapping and validation concepts, but only reports readiness — it does not calculate financial results or create an analysis.

Check your CSV readiness before creating an account
We check structure and mapping only. Files are processed transiently for this response, are not stored, and never create an analysis or use a quota.
Limits: up to 4,000 data rows and 600 KB per file. Sales and Inventory are required; Cost is optional.
Useful fields
SKU, revenue, units, dates, quantity on hand and unit cost are the core signals. Product name helps make the result easier to read.
What happens to gaps
Missing or partial cost is surfaced as a coverage limitation. It is not silently treated as zero.
