Product Csv Check

Check a product CSV's header row against Shopify's current columns. FREE.
Catches the failure that wastes the most time: a template copied from an
out-of-date guide, using column names Shopify renamed. Typical input
{"header_row": ["Handle", "Title", "Body (HTML)", "Variant Price"]}
returns {"ok": false, "missing_required": [], "renamed": [{"found":
"Handle", "use": "URL handle"}, ...], "unrecognised": [], "verdict": "..."}.
Use before an import, on the header row alone. Not for whether the values
in the rows are valid — check a handle with url_handle and a metafield key
with metafield_key_check. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "header_row must contain at least one column name"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| header_row | array | yes | The CSV's first row as a list of column names, exactly as written in the file, e.g. ["Handle", "Title", "Variant Price"]. |
| mode | string | no | "new" when creating products, where Shopify requires only Title; "update" when changing existing ones, where it also requires URL handle. Default "new". |
