Open two example supplier CSVs. Select both files and concatenate them using matching columns. Review the eight combined rows, then remove duplicates to leave six rows. Save the cleaned CSV and reopen it. Review the columns, including the exported index, before using it.
A simpler supplier workflow
From messy files to a CSV you can review.
When new supplier exports arrive, use the same visual steps to prepare your products and inventory for your next Shopify import.
Clean and combine
Inspect columns, filter unwanted rows, remove duplicates, and merge or concatenate files without writing code.
Export and review
Save your result as a CSV, then check its columns and values against Shopify’s import requirements before uploading.
Made for repeat work
The next supplier file doesn’t have to mean starting over.
Save a workflow for steps you repeat, then use it again when the next export arrives. Core CSV processing happens locally on your computer.
DataOlllo helps prepare your data; review the exported file before importing it into Shopify, especially product identifiers and required columns.
