About this format

A column-oriented data format from Apache, 2013. Values of the same column are stored together, so it compresses well and analyses fast. The standard for big data and data science; people do not open it directly.

What it can hold

Tables (columnar, compressed)
Types and schema
Nested structures

What it cannot

Human readability — it is binary
Row-by-row appends

When you convert it

Frequently asked questions

How do I convert a PARQUET file?

Drop the file into the window, pick the target format, and download the result. No account required.

Do I need to install anything?

No. It runs in your browser. A Windows installer is available separately if you prefer one.

What if the format I want isn't listed?

Every engine's capabilities are merged into a single graph, so unlisted pairs are chained automatically through intermediate formats along the least-lossy route.
