Export
Download a CSV from your current tracker, or save your spreadsheet as CSV. Keep the original file as a backup before changing column names.
Audit
Use the free audit to test matching quality. It checks a sample, shows recognised sets, and highlights rows that may need cleanup.
Tidy
Rename unclear headings, split mixed notes into useful columns where possible, and make set names/card numbers consistent before importing.
Import
Paid members can import matched rows into owned or wanted lists with quantity, condition, grade assumptions, and notes.
Maintain
Use filters, saved views, completion modes, exports, and card-page links to keep the collection easy to manage as it grows.
