Take a look at Mixtable. Mixtable is a spreadsheet like Google Sheets, but with all Excel-style formulas and behavior. And it seamlessly syncs to and from Shopify. You can easily paste the data from your CSVs into a Mixtable workbook and sync your data back to Shopify. See here for more on how to bulk edit your Shopify store's data.
