Dani Neguillo's Work | ContraWork by Dani NeguilloDani Neguillo
I automate business workflows with Python, Excel & AI
Supplier files → Shopify import CSV, with nothing guessed.
I built a small synthetic test of what my pilot delivers: two supplier files (an Excel sheet and a Windows-1252 CSV) with the usual problems. SKUs that lost their leading zeros, prices written as 89,90 / 89.9 / 1.099,00 / €34,95, an exact duplicate, the same SKU with two prices, a size typed as "M/L", and a price "1.099" that could mean either 1,099 or 1.099.
Result: 17 rows read, 9 variants under 6 product handles, 8 rows excluded. Every excluded row is in an issues sheet with its file, row and reason, and every transformation is traced row by row. The output is checked against Shopify's official CSV template; it was not tested in a live import, since the import stays with the store owner.
If you handle supplier catalogs for Shopify stores, the pilot is one supplier file, up to 500 rows, USD 169: https://contra.com/s/6XAcFFNX-supplier-catalog-files-shopify-ready-import-csv-pilot
