JSON Preview

Indented JSON is easy to read one record at a time and hard to compare across records. As a table, each object is a row and each key is a column, so you can see at a glance which records are missing a field, which have null, and where a value has an unexpected type or format.

Columns are the union of all keys across all objects, in the order they first appear. A key that only a few records have still gets a column, with blank cells elsewhere. That makes the table a quick way to check an API response against its documentation.

Nested objects and arrays are shown as compact JSON in their cell, so {"city": "Pune"} appears as {"city":"Pune"}. null shows as an empty cell, and numbers and booleans as plain text. To give nested fields their own columns, flatten the data first with Flatten JSON and preview the result in CSV Preview.

The input must be one valid JSON document: an array of objects, or a single object, which is shown as one row. If parsing fails, the browser's error message points to where the JSON breaks, which helps with a missing comma or an unescaped quote.

Copy or download a PNG of the whole rendered table, including columns scrolled out of view, cropped to the table's edges. The first 500 rows are rendered, and the total row count is shown.
