What JSON shape does the converter expect?

An array of flat objects — e.g. [{"id": 1, "name": "alice"}, {"id": 2, "name": "bob"}]. Each object becomes a ; the union of every key across every object becomes the header set.

Does the output include any styling?

No. The output is semantic HTML only — , , , , . Style it with your own CSS, or paste into a system that already has table styles (Bootstrap, Tailwind's prose, GitHub README rendering, email-template CSS).

Are HTML special characters escaped?

Yes. Cell values are escaped for &, , and " so you can't accidentally inject markup or break out of attributes. Safe to use with values that contain user-generated content.

What about HTML emails?

The output works in HTML emails, but you'll typically want inline styles and table-based layout. Wrap with style attributes (border, padding, background) before pasting into your email template — Gmail and Outlook strip blocks but respect inline styles.

What happens to nested objects in cells?

Cell values that aren't primitives are JSON-stringified inside the cell. The table stays one-row-per-object — the converter doesn't flatten nested keys into extra columns. If you want nested keys as separate columns, run the JSON through Flatten first.

Can I produce a Markdown table instead?

Yes — see the JSON to Markdown Table tool. Same input shape, different output. Use Markdown for READMEs and Notion; use HTML for emails, web pages, and HTML-only renderers.

Is the JSON sent to a server?

No. Conversion runs entirely in your browser. Your JSON never uploads — safe for internal exports, customer data, or anything you wouldn't paste into a third-party site.

Will the table sort or be interactive?

No — the output is plain semantic HTML. For sortable, searchable, paginated tables, use a frontend table library (DataTables, AG Grid, TanStack Table) and feed it the original JSON instead of pre-rendered HTML.

When Do You Need JSON to HTML Table?

HTML email templates: Outlook and Gmail respect inline-styled tables. Generate the table once from a JSON sample, wrap with inline styles, paste into the email body.

Static dashboards: Marketing, ops, internal tools — render JSON exports as a clean table in a one-page HTML report. No JS framework needed.

Documentation snippets: When Markdown tables don't cut it (need attributes, custom colspan, embedded HTML), reach for the HTML version. Paste into MDX, Docusaurus, or any HTML-aware doc site.

Legacy CMS systems: Old WordPress, Drupal, or custom CMS editors accept HTML but not Markdown. Render once, paste, ship.
