JSON to HTML Table

JSON is built for machines, not for reading. When a payload has to be shown to people — a review meeting, a support ticket, a wiki page, an email — a table is the format that works. Building that table by hand means flattening paths, deciding columns and escaping every value.

Convert JSON to HTML generates a styled HTML table from your document in one click. Key/value mode flattens any object into labeled rows; array mode turns arrays of objects into tables with dynamic headers. Preview it live, copy the snippet, and paste it anywhere.

• Two layouts: Key/value rows for objects, or dynamic columns for arrays of objects.
• Dot-path keys: Nested values are flattened into readable settings.theme style rows.
• Union headers: Array mode covers objects with differing keys automatically.
• HTML-escaped cells: Values are escaped so the snippet is safe to embed.
• Built-in styling: The generated table includes clean default CSS.
• Live preview: See the rendered table before copying.
• Copy and download: Export the full HTML snippet instantly.
• Private: All processing happens in your browser; nothing is uploaded.

1. Paste your JSON — an object or an array of objects.
2. Pick the layout: key/value rows or dynamic columns.
3. Check the preview below the input as it renders live.
4. Copy or download the HTML snippet.

Example 1 — Ticket attachments. A support engineer converts an error payload into a key/value table and pastes the HTML into the ticket editor — the team sees every field without opening the raw JSON.

Example 2 — Meeting slides. An analyst renders an array of customers as a table with columns for name, email and orders, then screenshots the preview for the slide deck.

Example 3 — Wiki documentation. A developer publishes a sample config as an HTML table in the team wiki, keeping the keys and values readable without any plugin.

Example 4 — Email reports. An operations engineer converts a status payload to a table and emails the snippet to stakeholders who should not have to read JSON.

• Human-readable: Complex JSON becomes a table people can scan.
• No dependencies: The snippet is self-contained HTML with inline styles.
• Safe by default: All values are HTML-escaped before insertion.
• Zero data movement: The document is converted locally and never uploaded.
• Instant results: Live preview renders with every keystroke.
