CSV Analyzers

Upload your Amazon Seller Central reports and get instant, actionable analysis. No AI guesswork — every calculation uses deterministic formulas you can verify.

100% Private — Your data never leaves your browser

All CSV parsing and analysis runs locally using JavaScript. Nothing is uploaded to any server. You can disconnect from the internet before uploading to verify. We do not collect, store, or transmit any of your Amazon data.

How it works

  1. Download a CSV report from your Amazon Seller Central account
  2. Upload it here — the file is read by your browser, not our server
  3. Get instant analysis with actionable recommendations

About our analysis

  • All calculations use deterministic formulas, not AI. 2+2 always equals 4.
  • Recommendations are based on rule-based thresholds (e.g., ACoS > your target = "reduce bid").
  • Category benchmarks are sourced from public Amazon data and industry reports, cited where used.
  • Unlike AI chatbots, our analysis is reproducible — same input always gives same output.
