Moving your LEGO inventory from Rebrickable to BrickLink is a common task for resellers expanding their sales channels. While both platforms track your collection differently, you can transfer most of your data with some manual work. The challenge is that Rebrickable focuses on set building while BrickLink centers on marketplace selling, so inventory formats don't match perfectly. Here's how to make the transfer work, plus smarter alternatives for serious resellers managing large inventories across multiple platforms.

Export your inventory from Rebrickable

Log into your Rebrickable account and navigate to your Parts List. Look for the "Export" option, which generates a CSV file containing your part inventory. This export includes part numbers, quantities, and colors, but uses Rebrickable's naming conventions and IDs.

The exported file will have columns for part ID, quantity, color, and condition. Note that Rebrickable uses different part numbering systems than BrickLink in many cases, especially for newer elements.

Convert part numbers and formatting

BrickLink uses its own part numbering system, which often differs from Rebrickable's. You'll need to manually cross-reference part numbers between the two systems. This is the most time-consuming step in the process.

Open your exported CSV in a spreadsheet program. Create new columns for BrickLink part numbers, BrickLink color IDs, and proper formatting. BrickLink's catalog uses different color names and numbering than Rebrickable, so expect to spend significant time on color matching.

Prepare your BrickLink import file

BrickLink requires specific CSV formatting for inventory imports. Your file needs columns for Item Type, Item No, Color ID, Quantity, Condition, and Price. Format your converted data to match these requirements exactly.

Set Item Type to "P" for parts, "M" for minifigures, or "S" for sets. Leave Price blank if you plan to set prices manually later. BrickLink's import feature is strict about formatting, so double-check column headers and data types.

Upload to BrickLink inventory

In your BrickLink store admin, find the "Mass Upload" tool under Inventory management. Upload your formatted CSV file and review any error messages. BrickLink will flag unrecognized part numbers or formatting issues.

Fix any errors in your CSV and re-upload. Once successful, review your imported inventory for accuracy before making items available for sale.

Why most resellers skip this process

The manual conversion between Rebrickable and BrickLink takes hours for even modest inventories. Part number mismatches create errors, and you'll still need to set competitive prices manually. Most serious resellers use tools that handle multiple platforms automatically rather than wrestling with manual imports between systems.
