Metafield Tool

Metafield data entry

Import a Matrixify product export and the metafield JSON captured by the Blink Metafield Grabber extension, then fill in every value in one big spreadsheet-style grid - with choice-list fields restricted to their real allowed values, and a Matrixify-ready CSV to export when you're done.

Nothing is uploaded anywhere. Both files are read entirely in this browser tab, and your edits auto-save to this browser's local storage as you go. That means closing the tab and coming back won't lose your work, but it's tied to this one browser - use Download CSV once you're happy with the data.
What it does
📄

Matrixify import

Reads a standard Matrixify product export (.xlsx or .csv) - one row per variant, exactly as Matrixify writes it.

🧩

JSON-driven columns

The extension's JSON decides which metafield columns stay. Anything not listed is dropped from view; anything listed but missing from your file is added as a new blank column.

✅

Choice lists, enforced

Fields the extension flagged as a Choice list only accept the exact values it captured - a dropdown for a single choice, removable chips for a list of choices.

🔗

Product vs variant scope

Product-level metafields show one merged, editable cell spanning every variant row of that product; variant-level metafields get their own cell per row.

Auto-save

Every edit saves to this browser automatically - a refresh or an accidental close won't lose your progress.

Matrixify-ready export

Download a CSV containing just the identifier columns and the metafields you edited, ready to re-import via Matrixify.

How to use
1

Export your products from Matrixify

Admin → Apps → Matrixify → Export → Products, as .xlsx or .csv. Drop it into the tool's first import box.

2

Capture your metafields with the Blink Metafield Grabber extension

Tick the metafields you need, run Capture all details so Choice list fields get their allowed values, then copy or download the JSON export.

3

Paste or upload that JSON into the tool

Every metafield in the JSON gets matched against your Matrixify file's columns (Matrixify's own Metafield: namespace.key [type] / Variant Metafield: ... header format). A metafield with no matching column yet is added as a new one so you can start filling it in.

4

Fill in the grid

Reference columns (Title, SKU, and similar) are read-only context. Metafield columns are editable:

  • Plain text or number fields - a normal text box
  • True/false fields - a checkbox
  • A single Choice list value - a dropdown of just the allowed values
  • A Choice list of multiple values - removable chips, plus a dropdown to add more

Product-scoped fields show one cell merged down every row belonging to that product, so there's never a risk of entering two different values for the same product by mistake.

5

Download your CSV

Click Download CSV for a Matrixify-ready file - identifier columns plus only the metafields you worked with - ready to re-import via Matrixify's own import flow.

Troubleshooting
?

A metafield's dropdown has no options

The extension flagged it as a Choice list but didn't capture any allowed values (e.g. its detail page wasn't visited). Re-run Capture all details in the extension and re-import the JSON.

?

A metafield was skipped

Its entry in the JSON has no captured namespace.key (metafieldMissing: true). Visit that field's detail page in Shopify with the extension active, then re-export the JSON.

Edits auto-save to this browser only - a different browser or device won't see them, and Start over wipes them intentionally. Download a CSV regularly once you've made real progress.
