What is JSON to HTML Table?
JSON to HTML Table transforms an array of objects into an HTML table. It collects the union of keys as columns and renders each object as a row, making API responses and data samples easier to read.
How It Works
The JSON is parsed and validated as an array of objects. The column set is the union of all keys in first-seen order, and every cell is HTML-escaped before the table is assembled.
Common Use Cases
- Documenting API responses
- Creating HTML tables for email reports
- Reviewing JSON exports without a spreadsheet
- Embedding tabular data in static pages
Technical Details
Parses JSON with JSON.parse and escapes ampersands, angle brackets and quotes. Nested objects and arrays are rendered as compact JSON strings.
