What File Formats Are Supported for Amazon Ads Report Imports?
← Back to How to Keep Amazon Ads Excel Reports Updated Without Rebuilding Them
Quick answer
Amazon Ads report imports are supported in CSV and XLSX file formats, with a maximum file size of 20MB per file for both scheduled and manual uploads. These two spreadsheet-compatible formats cover the majority of Amazon Advertising Console exports, including Sponsored Products search-term reports. Accepting both CSV and XLSX allows teams to work with raw data exports without converting files before bringing them into an analytics or management workflow. The file size cap helps ensure imports remain stable even for accounts with substantial advertising data.
In practice, most sellers export from the Amazon Advertising Console and upload the file directly. The Amazon Ads Report Analyzer accepts both CSV and XLSX uploads, so you can use whichever format your Amazon export defaults to without rebuilding the report.
CSV vs. XLSX: Which Format Should You Use?
CSV files are plain text with comma-separated values and tend to be smaller, which can be useful when your export is near the 20MB limit. XLSX files preserve formatting, multiple sheets, and native Excel features, making them easier to review manually before uploading. Both formats are accepted, so the best choice is usually the one Amazon generates from your report settings.
If you are working with a team, XLSX may be easier for pre-import review, while CSV reduces file size for very large datasets.
Working Within the 20MB File Limit
A 20MB cap applies to each file upload, whether you are importing manually or using a scheduled email delivery. Large accounts with daily search-term data can approach this limit quickly, especially when spanning multiple marketplaces or long date ranges.
- Export shorter date ranges to keep individual files under 20MB
- Filter by campaign or ad group before exporting when possible
- Use scheduled imports that split data across multiple files where supported
When This Matters for Report Import Workflows
Understanding supported formats prevents upload failures and keeps your data pipeline consistent without manual rework. If a tool only accepted CSV, for example, Excel users would need to export again in a compatible format before analysis. Knowing that both CSV and XLSX work up to 20MB means you can plan exports once and set up recurring imports without checking file type each time.
This is especially important when maintaining updated Amazon Ads Excel reports without rebuilding them from scratch.
