Frequently Asked Questions
What is the Shopify Metafield JSON Validator?
It is a free developer utility designed to test and validate JSON strings or structured payloads intended for Shopify product, variant, or customer metafields.
Why do Shopify metafield JSON values fail?
Common issues include trailing commas, unquoted keys, mismatched brackets, or unsupported types that violate Shopify Admin API or GraphQL schema definitions.
Can I format and beautify valid JSON payloads?
