Displaying JSON data on a webpage usually means writing repetitive table markup by hand, row by row. This tool automates that by taking a JSON array of objects and generating complete HTML table markup, complete with a header row derived from your object keys. It's a time-saver for developers building quick data dashboards, documentation pages, or email reports where a lightweight static table is enough. The generated markup uses semantic table, thead, and tbody tags so it's easy to style with your own CSS afterward. Since the conversion runs entirely in your browser, your data is never uploaded, and there's no account needed. Paste your JSON array below to get ready-to-paste HTML table code.

Frequently asked questions
What does this tool generate from JSON?
It generates complete HTML table markup - including table, thead, tbody, tr, and td tags - based on the keys and values in your JSON array.
Do I need a JSON array or can I use a single object?
An array of objects works best since each object becomes a table row; a single object can also be converted into a two-column key-value table.
Are the column headers automatically generated?
Yes, the header row is created from the unique keys found across your JSON objects, in the order they first appear.
Can I style the generated table afterward?
Yes, the markup uses plain semantic tags with no inline styles, so you can apply your own CSS classes freely.
Does it handle missing fields across records?
Yes, if some objects lack certain keys, those cells are rendered empty so the table structure stays consistent.
Is my JSON data uploaded to generate the table?
No, the HTML is generated entirely in your browser using JavaScript - nothing is sent to a server.
Can I preview the table before copying the code?
Yes, a live rendered preview is shown alongside the generated markup so you can check the layout first.
