Quick answers about validating Apple Wallet pass.json files.

What does the pass.json validator check?

It checks required PassKit fields, pass style structure, barcode fields, color values, location shape, expiration dates, and common field limits.

Is my pass.json uploaded?

No. Validation runs in your browser, so the JSON you paste or upload stays on your device.

Can this replace Apple's validation tools?

No. Use it as a quick first pass while building or reviewing a wallet pass. Always test the final .pkpass package on Apple Wallet.

Use these next when you need to inspect the full pass package or estimate loyalty value.

Open a full .pkpass package to inspect pass.json, images, manifest hashes, signatures, and a rendered preview.
