Use ChartMkr to generate a chart from JSON

  1. Reshape your JSON into a simple table format (series/value or stage/value).
  2. Paste the table (or paste your JSON content) into the generator.
  3. Adjust the title, labels, and styling, then export a PNG.

Export and reuse (for reporting)

  • Export PNG: Use the downloaded image in PowerPoint, Keynote, or Google Slides.
  • Reuse the structure: Keep the same chart configuration and update data when values change.
  • Sign in to save: When you sign in, your charts are saved automatically for reuse.

Why ChartMkr instead of Excel or code

  • Less formatting work: Start from data and focus on the message, not chart mechanics.
  • Cleaner output: Get presentation-ready visuals without custom coding or complex Excel formulas.
  • Faster iterations: Make small edits and export again when you need an updated version.

Frequently asked questions

You can't upload a JSON file, but you can paste JSON content directly into the generator input box. If needed, reshape it into a small table first.
