Can I merge Amazon FBA inventory, settlement, and advertising CSVs even though they have completely different columns?

Yes. Deliteful performs a full outer join on all column names across every uploaded file. Every column from every Seller Central report appears in the merged output, and rows from reports that lack a given column receive an empty cell — no data is dropped.

How do I use the merged file to calculate per-ASIN profitability?

After merging, open the file in Excel or Google Sheets and use VLOOKUP or SUMIF formulas to match ASINs across the rows from each source report. Deliteful handles the consolidation — the profitability calculation happens in your spreadsheet.

Does the tool work with Amazon settlement reports, which have a different structure than inventory reports?

Yes. Settlement reports, FBA inventory reports, and advertising reports can all be uploaded together. The column alignment is automatic regardless of how different the report structures are.

Can I merge reports from multiple Amazon marketplaces (US, UK, EU) into one file?

Yes. You can upload CSVs from any combination of marketplaces. If marketplace-specific columns differ, they all appear in the merged output with empty cells where a given marketplace report lacked that column.

Merge Your Amazon FBA Inventory, Settlement, and Ad Report CSVs Into One File

Amazon sellers downloading FBA inventory reports, settlement statements, and Sponsored Products ad reports from Seller Central get three CSVs with completely different column structures every month. Deliteful's CSV Merge tool combines all of them into a single unified file — columns aligned automatically — so you can cross-reference ASIN performance, fees, and ad spend in one place.

Seller Central exports are notoriously inconsistent: the FBA Inventory report uses 'fnsku' and 'your-price', the settlement report uses 'amount-type' and 'amount-description', and the advertising report uses 'Campaign Name' and 'Impressions' — none of which overlap. Sellers who want to see total profitability per ASIN (revenue minus FBA fees minus ad spend) have to manually reconcile these three files in Excel, which takes 30–60 minutes and is error-prone. Deliteful merges all three into one CSV in seconds, with every column from every report preserved and missing values filled with empty cells.

The merged file is stable enough to use as a repeatable monthly input for your profitability analysis. Column order follows first-encounter across your uploaded files, so if you always upload FBA inventory first, those columns anchor the left side of the output. Row order is preserved within each source report. The UTF-8 output opens cleanly in Excel or Google Sheets for pivot table analysis or VLOOKUP-based ASIN matching.
