Historical Data Import
Prepare, validate and load historical studio records.
Step 1
Prepare workbook
Use the generated workbook without renaming sheets or column headers. Leave unused sheets empty.
Step 2
Select and validate
The file is checked before anything is written to Supabase.
Step 3
Run LSM import
Records load in dependency order. Run this against a clean historical dataset to avoid duplicates.
warning
Download a database backup first. A failed import can leave successfully imported earlier rows in place.
