Fieldloader – bulk edit variant metafields by CSV

Shopify's product CSV import drops a variant metafield column without saying so: the import reports success and the values are not there. Fieldloader exports the field instead, takes your edited file back, and shows what would change before it writes anything.

Get it on the Shopify App StoreHow the file works

See it in action

The app as it runs inside the Shopify admin, on a development store of 5,032 variants. Select a screenshot to open it full size.

  • Fieldloader's home screen: a green line reading nothing would change, all 5,032 rows came back exactly as they went out, the field and the timings under it, and a summary of the catalogue with 120 products and 5,032 variants.
    The first run: the file goes out and comes back unchanged
  • An import preview: a green line reading 5 values would change, then 5,032 rows read from five-changes.csv, new values 5, changed 0, cleared 0, already correct 5,027, can't be imported 0 — and a table of the five changes with their line numbers, the variant handle and SKU, what each holds now and what it would become.
    What the file would do, before it does it
  • An import that will not run: a red line reading 5 rows can't be imported and that nothing is written while anything is wrong, above a table of problems by line and column — an id no variant has, a row repeated from an earlier line, a row naming nothing, a value one character too long, and a line break in a single-line field.
    Every bad row, with its line and the reason
  • Fieldloader's import history: an import and the rollback of it, each with when it ran, which field it wrote, how many values were written, and a button to roll it back or redo it.
    Ten imports back, each with a way out
  • Fieldloader's Metafields screen: what the field belongs to set to each variant, then name, namespace, key, what it holds, an optional description, and a checkbox to show it on the product page in Shopify.

What it does

Export one metafield, edit the file, send it back — and see the whole of what it would do first.

  • A row for every variant

    The export is one row per variant, including the ones with no value yet: id, handle, sku, value. The id leads because it is the only column that identifies a row for certain.

  • Edited where you already work

    Open it in Excel or Google Sheets and send it back. A file saved with semicolons, the way Excel does on a Dutch or German computer, is read as it is.

  • The diff, before anything is written

    How many values are new, changed, cleared and already correct — counted against what Shopify holds right now — with every changed row listed by line.

  • Bad rows named, never dropped

    A row that cannot be imported is listed with its line, its column and what is wrong with it, and nothing is written while anything is wrong.

  • Undo in one click

    Every import is kept with the values as they were just before it. Roll it back and those go in again; put the rollback back and you are where you were. The last ten imports are kept.

  • Product metafields too

    Variant metafields are the ones Shopify's CSV will not carry, but a product metafield goes through the same export, diff and rollback.

A rollback writes the values back as they were immediately before its import, so a value edited in the admin since is overwritten. The screen says so before you press it, and putting the rollback back undoes that in turn.

What it costs

Both plans do everything above. The only difference is how many values one import may write.

  • Free

    500 values per import

    Values written, not rows in the file — so exporting five thousand rows, filling in twenty and sending the whole file back stays free. Exporting, checking a file and rolling an import back are never counted.

  • Standard

    $19 a month

    The same app with no limit on the values an import writes. A file holds up to 50,000 rows on both plans.

Before you install

A store to look around, a page about the file, and an address to write to.

  • The demo store

    Twelve products, sixty-two variants and four variant metafields, all written by Fieldloader. fieldloader-demo.myshopify.com — opened from the App Store listing, Shopify lets you past its password page; from anywhere else it asks for one.

  • What the file looks like

    The app's own help page walks through a CSV of variant metafields, column by column: bulk edit variant metafields with a CSV.

  • Support

    Questions, or a file that will not import the way you expect: hello@askomni.app. The same address the listing gives.
