How to use it
- Paste your JSON into the input box, upload a .json file, or drop a file onto the box.
- The HTML table appears as you type.
- Copy the result or download it as a .html file.
Good to know
- Nested objects become dotted column names, so supplier.city gets its own column. Arrays become numbered columns: tags.0, tags.1 and so on. If the data is a list, each entry becomes one row.
- Special characters are escaped, so a value like <b> shows as text instead of becoming markup.
About the formats
JSON
JSON (JavaScript Object Notation) stores data as nested objects and arrays. It is the standard format for web APIs and the config files of most JavaScript projects.
HTML table
An HTML table uses <table>, <tr> and <td> tags to show rows and columns on a web page. The output here is plain, unstyled markup you can paste into a page or an email template.
Questions
- Is my data uploaded anywhere?
- No. The conversion runs in your browser with JavaScript. Your data never leaves your device, and the tool keeps working if you lose your connection after the page has loaded.
- What happens to nested JSON?
- It is flattened. Each nested value gets a column named after its path, such as supplier.city or tags.0. Empty lists and empty objects become empty cells.
