Tips

• You can use ?url= to load a file from a url. For example, parquet-viewer.xiangpeng.systems/?url=https://raw.githubusercontent.com/tobilg/public-cloud-provider-ip-ranges/main/data/providers/all.parquet will load the file from github. parquet-viewer is smart enough to only download the data that is relevant to your query, usually a few KBs, even if the file is large.

Development

It compiles Parquet, Arrow, Datafusion, OpenDAL to WebAssembly and uses it to explore Parquet files, more details.
