Start with the files your suppliers actually send
Bluestone documents CSV/XLSX imports with suggested and saved mappings, a review step, and support for variants, relations, and assets. That is useful when suppliers already deliver structured tables. If a specification is buried in a PDF or spread across documents and product pages, test the preparation needed before that import. Lasso brings those sources into working batches for extraction, mapping, and enrichment. Compare the complete path from received material to approved attributes, including the manual preparation each route requires.
