Frequently Asked Questions

What file formats are supported?

Any CSV file with a header row. We support standard CSV with comma delimiters. The tool auto-detects review text and rating columns by header keywords.

Is my data uploaded to your servers?

No. All processing happens in your browser using JavaScript FileReader. Your data never leaves your device.

What does the "Quick Insight" mean?

It is a rule-based observation — for example, if your 1-star percentage exceeds a typical benchmark. It is not an AI analysis. For deep insights, use the full AI report.
