Before importing: quantities are added

Check for sets already recorded in Superbrick. Remove overlapping rows from the file or plan to reconcile their quantities afterward. Keep a copy of the original export so you can check the result.

Use the expected columns

The required headings are exactly Set Number and Quantity. Quantities must be positive whole numbers, and the file must be UTF-8. Other export columns may be present, but this import reads the set number and quantity only.

10305-1,1

Import in the app

  1. Export the owned sets you want to move from Rebrickable as a CSV file and save it to Files.
  2. Open Superbrick → You → Lists → New list.
  3. Choose Import from Rebrickable, then Choose File.
  4. Select the CSV and complete the import flow.
  5. Read the result summary: imported sets, skipped entries and parsing errors.
  6. Check the new list and owned quantities against the original file.

What carries over—and what needs review

ImportedReview separately
Set numbers matched to the catalogAny set numbers the app could not match.
Positive owned quantitiesExisting quantities that the import adds to.
A new list of matched setsPurchase prices, dates, notes and condition.
Set recordsParts and separate minifigure inventories are not imported.

Fix problems without importing everything again

If a row is rejected, check its column headings, set number and quantity. Fix the rejected rows in a separate file instead of importing the entire successful file again. A catalog mismatch needs to be resolved; changing the quantity will not fix an unknown set number.

The import marks imported set records as Sealed, including sets already recorded. Review the build status afterward if your copies are built or used. Collection and list limits still apply, and the app will show any Pro requirement.

An overlap example before you import

Suppose Superbrick already records one copy of 10497-1 and your CSV contains a quantity of two for the same set. Importing that row adds two and leaves three owned copies. If you own only two in total, that row is not an instruction to replace one with two.

Prepare the file around the additional quantities you intend to add, or reconcile the overlap before importing. A small file is easier to check than repeating a whole collection export.

Questions collectors ask

Can I import a Rebrickable CSV on iPhone?

Yes. Save the compatible UTF-8 CSV to Files, then choose Import from Rebrickable from the new-list flow in Superbrick. The same workflow is available on iPad.

Will my purchase costs and condition transfer?

No. The importer reads set numbers and quantities. Imported set records are marked Sealed, including existing records, so review their build status afterward.

What if only some rows fail?

Correct only the rejected rows in a separate file. Importing the successful rows again adds their quantities again.
