Data Viewers

Raw data is easier to read as a table. Rows line up, columns get headers, and a missing field or a stray value stands out. These viewers take JSON, CSV or a PHP array and render it as an HTML table without you writing any code.

Paste the data, upload a file or fetch it from a URL. The JSON viewer expects an array of objects and turns each key into a column. The CSV viewer lets you choose the delimiter and treats the first row as headers. The PHP array viewer parses both array() and [] syntax. All three handle large inputs and scroll horizontally when there are many columns.

Use them to check an API response before you write the parser, to inspect an export before importing it somewhere else, or to share a quick look at a dataset with a colleague.
