ChartPixel turns messy spreadsheets, surveys and webpage tables into interactive charts, written insights, forecasts and statistical tests. Upload a file, and the platform cleans and enhances the data, picks the most useful chart types, explains what each one shows, and lets you chat with your data.
Upload Excel or CSV files, or read tables from a webpage, and the platform tidies the data and picks the most insightful chart types for you.
Each chart comes with a written description, key takeaways and the supporting statistics, so findings are presentable immediately.
Ask questions of your dataset and its charts in natural language to dig into correlations and outliers without writing queries.
Run trend forecasts, statistical tests, sentiment analysis on comment fields and maps generated from postcode data.
