You do not have to retype anything. Export your collection from Brickset as a CSV, open Collection in SetSquad, choose Import, and pick the file. SetSquad works out which app the export came from on its own, so there is nothing to map or configure. Rebrickable exports work exactly the same way.
It takes about two minutes whether you own 30 sets or 500. CSV import is a Pro feature, and every Founding Member has it for their first year, so for most people switching across it costs nothing. The detail is at the bottom of this page.
What you need
A CSV export from Brickset or Rebrickable. Both let you download your collection from your account page. You do not need to clean it up or rename any columns first.
What carries across
From a Brickset export, SetSquad reads:
| Brickset column | Becomes |
|---|---|
Number | The set, matched against our catalogue |
QtyOwned | How many copies you own |
Own | Marked as owned |
Want | Marked as wanted |
A set marked neither owned nor wanted comes in as previously owned, so your history is not thrown away. From a Rebrickable export it reads set_num and name and does the same matching.
If the file is not a recognised export, SetSquad says so and names the columns it expected (Number and SetName for Brickset, set_num and name for Rebrickable) rather than failing silently.
What happens to sets we do not have
Our catalogue covers LEGO sets from 2000 onward. Anything in your export that we cannot match is counted and reported back at the end of the import, so you can see exactly what did not come across instead of discovering a gap later. Nothing is dropped quietly.
After the import
This is where SetSquad does something the app you exported from does not: it times your builds. Once your collection is in, start the timer on your next build and it records your time bag-by-bag, saves your personal best, and ranks it against everyone else who has built that set.
If you want to know what you are in for before you start, every set has a build-time page with an estimate you can read without an account.
What it costs
Being straight about it: CSV import sits behind Pro, alongside bulk add and CSV export. On a free account the Import CSV option is marked PRO and opens the upgrade screen rather than the file picker. A free account also tracks 30 sets, which is the limit you would meet anyway when bringing a few hundred across.
The way most people avoid paying for this is the Founding programme. The first 500 accounts get unlimited sets, unlimited timed builds, import and export, and no ads, for twelve months, with no card and nothing to cancel. That is the year to get everything catalogued in. What happens when it ends is covered in is there a free LEGO collection tracker.
And whenever you want your data back, SetSquad exports the whole collection as CSV: set numbers, names, status, condition, quantity and purchase prices. Being easy to leave is part of being worth staying with.
