Split Amazon Flat-File Catalog Exports by Category, Marketplace, or Status

Amazon sellers managing large catalogs across multiple categories or marketplaces regularly export flat files that need to be broken out before uploading, auditing, or sharing with a prep center. Deliteful's Excel Split by Column tool eliminates the manual filter-and-save cycle that slows down catalog maintenance.

Amazon flat-file exports — whether pulled from Seller Central inventory reports, bulk listing templates, or third-party tools like Helium 10 or Jungle Scout — often consolidate thousands of ASINs in a single sheet. When you need to isolate a specific category for a repricing update, separate FBA from FBM listings, or hand off a subset to a virtual assistant or prep center, you need those rows in their own file. Filtering manually and saving a copy for each category across a 5,000-SKU catalog is the kind of task that takes an hour and is easy to get wrong.

Deliteful reads your Excel file and produces one .xlsx per unique value in whichever column you specify — 'product-type', 'fulfillment-channel', 'item-condition', 'marketplace', or any custom tag column you use. Each output file contains the full header row and only the matching rows, ready to re-upload or forward. The tool handles up to 200 unique values per run, covering virtually any Amazon catalog.

Frequently asked questions

How do I split an Amazon flat-file export by product category?
Upload your flat-file Excel export to Deliteful, enter the column header for your category field (commonly 'product-type' or 'item-type-keyword'), and the tool generates one .xlsx per category with only those ASINs and the original header row.
Can I split by fulfillment channel to separate FBA and FBM listings?
Yes — enter 'fulfillment-channel' or whatever your export uses for that field, and Deliteful outputs one file per unique value, giving you clean FBA and FBM subsets.
Will the column headers in my flat file be preserved in the output files?
Yes — every output file includes the original header row from your flat file, so the structure is preserved and outputs are ready for re-upload or further editing.
What happens to ASINs with a blank value in the split column?
Rows with empty values in the specified column are collected into a single output file. No ASINs are dropped from the dataset.
Does this work with flat files downloaded from Seller Central?
Yes, as long as the file is saved as .xlsx or .xls with consistent column headers. Deliteful reads the first worksheet containing the specified column.
