Combining Amazon Ads Reports Across Accounts & Marketplaces
← Back to How to Prepare Amazon Ads Export Data for Power BI or Looker Studio
Quick answer
Combining Amazon Ads reports from multiple accounts or marketplaces is a data preparation step that makes cross-account analysis possible in Power BI or Looker Studio. The process involves aligning column names and formats, appending rows into a single sheet or table, and adding account or marketplace identifiers to each record. When done correctly, the combined dataset supports filtering by region, brand, or account while preserving metrics such as spend, sales, clicks, and ROAS without double counting.
If you manage Amazon Ads across several seller accounts or marketplaces, merging exports is often the fastest way to get a complete performance view. The goal is to create one clean table instead of juggling separate files. A consistent structure helps you avoid errors and makes later dashboards much easier to maintain.
Align columns and data formats first
Amazon Ads reports can vary in header names, date order, and currency formatting depending on the marketplace or export view. Before appending files, check that every export uses the same column labels for campaign, ad group, impressions, clicks, spend, sales, and ROAS. Convert all date fields to the same format and all currency values to a single currency if you plan to compare totals across regions.
- Standardize header names before appending rows
- Use ISO date format to avoid regional sorting issues
- Keep metric columns in the same order in every file
Keep account and marketplace identifiers
When you append reports, source context can disappear quickly. Add a column for account name or Seller Central ID and another for marketplace code. These identifiers let you filter the combined dataset by brand, region, or account without guessing where a row came from. It also prevents you from accidentally blending metrics from accounts with different currencies or time zones.
If your team works with multiple accounts regularly, the Amazon Ads Dashboard by Todoza consolidates Amazon Ads reports into a unified view with cross-account visibility and trend comparison.
When this matters most
Manual merging is fine for a one-off review, but it becomes risky when you need weekly updates, client reporting, or cross-marketplace comparisons. In those cases, choose a process or tool that preserves identifiers and handles scheduled imports. For Sponsored Products search-term reports, Amazon Ads Report Analyzer supports multiple Amazon accounts and nine marketplaces, which can reduce repeated manual work.
