How to turn an LDraw parts list into a BrickLink wanted list

1. Open your file. An LDraw model (.ldr or .mpd), a BrickLink wanted list, or a CSV. Studio can export LDraw. Submodels are counted as many times as they are used.
2. Choose what you want. A BrickLink wanted list, a LEGO Pick a Brick file, or a CSV with every number.
3. Settle anything unclear. Each line is ready, needs a choice from you, or is listed as not converted, with the reason. Nothing is guessed.
4. Download and upload. On BrickLink, upload under your wanted list using its XML format. On Pick a Brick, use the upload option on LEGO's page.

How much will convert?

Across 4,569,624 pieces in our set inventories, measured October 31, 2026, this share has a number in each system. Your file may differ: patterned parts, custom parts and very old files convert less often.

What it cannot tell you

It converts numbers. It does not check stock or say what a part costs. Pick a Brick stocks only some pieces, and where a part and colour have several element IDs we use the highest, which is usually the newest, so LEGO may still report a piece as unavailable. Pick a Brick has been reported to take 400 different elements of up to 999 each, so a longer list becomes several files. Minifigures and sets in a BrickLink list are left out and counted. Only part and colour numbers are looked up: your file is never sent to us. Renamed LDraw parts are matched using the rename list in the LDraw parts library (CC BY 4.0).
