PREFLIGHT CHECK
Check the 5,000-item limit, duplicate variation IDs and invalid stock values before a STORES inventory CSV upload.
🔒 Analysis runs in your browser. The CSV file itself is not uploaded to BlueprintLab.

The tool does not claim to verify live service-side master data, account-specific state, or network reachability that cannot be established reliably in-browser. The service’s own validation remains authoritative.
STORES inventory CSV relies on Variation ID and the “updated stock” column. Missing either column is treated as an error because the original inventory CSV header may have been altered.
The checker also catches blank/duplicate variation IDs and files over the 5,000-item upload limit.
STORES asks you to choose absolute overwrite or relative increase/decrease before downloading the CSV. That means the CSV contents alone might not prove which mode was selected.
The checker validates integer/unlimited syntax, but does not label every negative or large value as an error when interpretation depends on mode.
In relative mode, the downloaded current stock is not live. Purchases or cancellations during editing can change inventory before upload.
STORES also documents clamping relative results above 9,999 to 9,999 and below 0 to 0, so the starting inventory matters.
ERROR covers missing headers, blank/duplicate IDs, over-limit files, and nonnumeric stock text. WARNING means the value needs review in the selected STORES update mode.
