How do you update just the information in one column of your product data

[Artist122]

Trying to figure out how we can download and import back just specific columns and information on products with out having to upload the whole products file each time , if you leave out one columns information when you re-upload it erases that info from the item. Or if we have multiple images on our items we have to make sure all of these are in the upload still or it will remove all the additional images also.

Always check the manual: https://help.shopify.com/en/manual/products/import-export/import-products#overwriting-csv-file

• If a non-required column in the import CSV file is blank, then the matching value in the product list is overwritten as blank.
  • For example, the Vendor value in your existing product list is John's Apparel, but the Vendor column is blank in the CSV file that you import, then the John's Apparel is overwritten as blank.
    
    
• If a non-required column isn’t included in the import CSV file, but is included in the existing product list, then the value in the product list remains the same.
  • For example, if the Variant image URL column is included in the existing product list, but that column isn’t included in the import CSV file, then the value in the product list remains the same.

SO – if the column is in the file, but the value is empty, then this field will be emptied.
If the column is not in the file, the field value will be left untouched.

For example, if you want to update only prices, only leave the following Columns:
Handle, Title, Option1 Name, Option1 Value, Variant Price (option Name/Value pairs as needed)

Handle and Title are 2 required columns.

For example, for my single option products, the price update CSV is like this:

“Donation” product has prices updated – images and other data are intact:

Use Google Sheets to avoid invalid CSV file.
Consider using Matrixify app for more flexibility.

Shopify’s native importer is pretty all or nothing, which is why this feels harder than it should. If you only want to update one column, the safest approach is exporting products, editing just that column, and reimporting with all other columns left exactly as-is. Even small header or formatting changes can cause issues, so consistency matters.

If you’re doing this often, apps like Altera make this a bit less painful by validating files and letting you update specific fields without breaking the rest of the data. Otherwise, it’s worth browsing a few other bulk edit apps in the App Store to see which workflow fits you best.
