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.

• You can use parquet-viewer.py in utils to open a local file. Only works on Chrome or Firefox (not Safari).

./parquet-viewer.py /path/to/your/file.parquet
