Check, review, then submit.

Preflight an item workbook

1. Download a fresh Item Spec 5.0 item setup template from your Seller Center account for the intended category and feed type.
2. Keep the template’s sheet names and first six header rows intact. Save the original .xlsx file.
3. Choose Preflight and add both the fresh template and your populated workbook. You may also add an Activity Feed report.
4. Run the local scan. Review template diagnostics and the free findings before deciding whether to activate a project.
5. Review each suggested repair. Download a separate repair copy, compare it with the original, and submit it through Seller Center yourself.

Decode an Activity Feed report

Choose Decode and add an .xlsx or .csv Activity Feed report. Spec Doctor groups interpretable errors and explains what to inspect. Report-only mode does not create a repaired item workbook; add the original item workbook and template to Preflight to evaluate supported cell repairs.

Supported scope

The app targets recognizable .xlsx Item Spec 5.0 templates for MP_ITEM, MP_WFS_ITEM, and MP_MAINTENANCE. Each file must be at most 25 MB, with at most 2,000 populated item rows. Encrypted, signed, damaged, macro-enabled, legacy binary, and unrecognized workbooks receive diagnostics rather than a paid repair offer.

Checks cover supported structure, definitions, required fields, closed lists, identifiers, variants, and WFS cross-tab relationships. Category policy, Trust & Safety decisions, product authenticity, and seller-account validation are outside the tool’s scope. A template can contain rules the app cannot safely interpret; those limitations are shown with results.

Licenses and seven-day rescans

After purchasing through the app’s checkout link, copy the license key from your Lemon Squeezy receipt into Activate license. Keep the same browser project for rescans during its seven-day window. Starting a new project uses an unused credit; re-entering the key does not renew an existing window.

If checkout is unavailable, the store has not completed payment setup. You can still run the sample and free preflight. For a pending or failed paid activation, use the store contact in your receipt and include the order number and project ID. Your original workbook is never overwritten.

Start with the sample

The sample uses manufactured data to demonstrate findings, selected repairs, and downloads. It is not an official Walmart template and cannot demonstrate that a real submission will pass Walmart’s validator.
