About JSON Chart Maker
Paste a JSON array of objects, then pick which key supplies the X axis and which supplies the Y values. The tool renders the data as a line, bar, or pie chart and lets you switch types without re-entering anything. When the chart looks right, download it as a PNG image.
Parsing and rendering happen entirely in your browser, so the data you paste is never sent to a server. It is a quick way to sanity-check an API response, turn a small dataset into a visual for a report, or compare values without opening a spreadsheet.
Frequently asked questions
- What JSON shape does it expect?
- An array of objects where each object has consistent keys, so one key can map to the X axis and another to the Y axis.
- Can I export the chart?
- Yes. You can download the rendered chart as a PNG image for use in documents or slides.
- Which chart types are supported?
- Line, bar, and pie charts, and you can switch between them without re-pasting your data.
