Steps 1-2

Upload and check data

JSON array or data objectUse an array of objects, or an object with a data array. Nested objects are flattened into dot-separated fields.[{"month":"Jan","revenue":12400}]

Product usage metrics gives JSON to Chart a different data shape for checking recommendations, controls, and exports.

Use case

JSON to Chart workflow

JSON to Chart is for API responses and analytics payloads. It works with product adoption, activation, and retention metrics, adds nested key flattening and JSON path-friendly preview, and keeps the preview, checks, and exports tied to the data you entered.

From input to export

  1. Start with the product sample or paste your own JSON data.
  2. Load a sample that resembles your data shape.
  3. Review detected fields and recommendations before export.
  4. Export Chart, Flattened table after the checks explain any remaining context or readability issues.

When to use

  • Use JSON to Chart when you need to turn small data into a clearer chart.
  • It is a good fit for API responses and analytics payloads.
  • It works best when your data resembles product adoption, activation, and retention metrics.

When not to use

  • Do not use this workflow for deeply nested documents with mixed object shapes.
  • Do not publish the result until title, unit, source, and export size have been reviewed.
  • Use another chart preview when the recommendations explain a better fit.

Controls that matter

  • Choose the reader goal before accepting the first chart.
  • Review X and Y field mapping after import.
  • Use sorting or Top N when category labels are long.

Input and method

  • The parser normalizes rows into a browser-side table and never requires an account.
  • Field detection classifies product adoption, activation, and retention metrics into number, date, category, or text fields.
  • The recommendation rules look for date, category, and numeric fields before choosing the first preview chart.
  • The score combines data readiness, field mapping, chart fit, labels, accessibility, and chart export readiness.

Checks before export

  • Using JSON to Chart with data that is better suited to deeply nested documents with mixed object shapes.
  • Exporting before adding a clear title, unit, or source note.
  • Ignoring the page limit: this workflow is not intended for deeply nested documents with mixed object shapes.
  • Treating the score as approval instead of reviewing the specific fixes.

Export options

  • PNG and SVG exports use the current chart preview and selected size.
  • Markdown and mini report exports include title, source note, detected fields, score, and fixes.
  • HTML, JSON config, clean CSV, and alt text are available from the secondary export panel when data is valid.

Output limits

  • Very large datasets should be summarized before using this browser-side tool.
  • Avoid this workflow for deeply nested documents with mixed object shapes.
  • Image-only chart recognition, cloud storage, and collaborative editing are not part of this version.
  • Generated summaries should be reviewed before publication.
