Data to Chart Tools
Use these pages when the starting problem is the format: a CSV export, an Excel workbook, a JSON payload, a Markdown table, or copied rows from a spreadsheet.
Workflow
Paste or upload
Load a small dataset, then check how headers, rows, and nested fields were interpreted before trusting the chart.
Inspect fields
Confirm which fields are numeric, date, category, or text so the recommendations match the data shape.
Export the result
Move from raw rows to a chart, field summary, cleaned table, or report-ready asset.

Questions before you start
What JSON shape works best?
Use an array of objects or an object with a data array. Nested objects are flattened into dot-separated fields.
Can I use Excel files?
Yes. XLSX files are parsed in the browser and converted into table rows for charting.
