JSON File

File extension	.JSON
Category	Document File
Description	JSON, or JavaScript Object Notation, is a lightweight data interchange format used for exchanging data between systems. It is a text-based format that is easy for humans to read and write, and easy for machines to parse and generate. JSON is commonly used for web APIs because it is simple, efficient, and widely supported by programming languages. JSON consists of key-value pairs, with the keys being strings and the values being any valid JSON data type, including numbers, strings, objects, arrays, and boolean values. The syntax for a JSON object is enclosed in curly braces { } and the key-value pairs are separated by commas. JSON is a versatile format that can be used for many different purposes, including configuration files, data storage, and communication between web applications. Its simplicity and widespread support make it a popular choice for developers.

HTML File

File extension	.HTML
Category	Document File
Description	HTML allows creating structured documents and web pages. HTML file contains command tags in angular brackets that mark out each element like title, paragraphs, quotes, links, lists, etc. Web-pages generated with HTML have .html extension (for a static web-page). HTML code is processed by a browser, while user sees only the text and other elements of the page without any tags. The source code can be viewed separately. HTML files can be edited in a common text editor like a TXT file.

I convert API responses to HTML tables for quick human review during testing — the rendered output is clear and requires no extra formatting on my part.

JSON to HTML — Frequently Asked Questions ▼

How does the converter decide which keys become columns?

If the top-level JSON is an array of objects, each object's keys become the table headers, and each object becomes a row. The converter scans the array to collect every key — so missing fields just appear as empty cells, never broken rows.

What if my JSON is a single object, not an array?

A single object is rendered as a two-column key/value table. Each property occupies one row, with the key in column one and its value in column two.

How are nested objects and arrays handled?

Nested structures are flattened into the cell — either as a comma-separated list or as a small nested table — so the row layout stays intact. Deeply nested data may be more readable in JSON tree form.

Is the table styled?

The output uses plain semantic HTML — <table>, <thead>, <tbody> — with no inline CSS. Drop the table into a page with Bootstrap or your own stylesheet and it picks up the styling automatically.

Are special characters escaped?

Yes. HTML special characters in JSON values (<, >, &, quotes) are escaped so the output is safe to paste into any HTML document without breaking the markup.

What about Unicode and emoji?

JSON's native UTF-8 strings pass through unchanged. The HTML output is UTF-8, so emoji and non-Latin characters render correctly in any modern browser.

Can I convert NDJSON (newline-delimited JSON)?

This page expects standard JSON. For NDJSON files (one JSON object per line), wrap them as a JSON array first — most editors can do this in a couple of find-and-replace operations.

Convert JSON to HTML — Render API Data as a Browsable Table

JSON is the format every REST API returns, but a raw .json file is illegible to anyone who isn't reading the curly braces. Converting JSON to HTML gives you a styled table — headers from the object keys, rows from the array elements — that you can open in a browser, paste into a report, or email to a non-technical colleague. Drop your .json file above.

What Is JSON?

JSON (JavaScript Object Notation) is the data format defined by RFC 8259, originally specified by Douglas Crockford in 2001. It encodes nested objects, arrays, strings, numbers, booleans, and null. JSON is the native payload format of nearly every modern web API — Twitter, Stripe, GitHub, AWS — and the default serialisation in JavaScript, Python, and most modern languages.

What Is HTML?

HTML (HyperText Markup Language) is the document language every web browser renders. The current standard is HTML5, maintained by the WHATWG. An HTML table uses <table>, <thead>, <tbody>, <tr>, and <td> tags that browsers display as a grid, search engines index, and screen readers announce.

JSON vs HTML — Format Comparison

Property	JSON	HTML
Year	2001 (Crockford), 2017 (RFC 8259)	1993 (HTML 1.0), 2014 (HTML5)
Purpose	Data interchange	Document display
Structure	Nested objects and arrays	Semantic tags + tables
Browser rendering	Raw text	Visual layout
Typical consumer	Programs, APIs	Humans, browsers
Styling	None (pure data)	CSS-styleable
Email-ready	No	Yes (inline tables)

When Do You Need JSON to HTML Conversion?

Share API response data with a non-technical stakeholder
Build a quick dashboard or status page from a JSON export
Paste a tabular view into an email, ticket, or document
Generate a printable report from a JSON data dump
Embed JSON-sourced data inside an existing HTML page or CMS
Inspect a deeply-nested response in a more scannable layout

Scripted Conversion
