Datasette plugin that adds custom SQL functions for executing jq expressions against JSON values.

Install this plugin in the same environment as Datasette to enable the jq() SQL function.

Usage:

select jq(
    column_with_json,
    "{top_3: .classifiers[:3], v: .version}"
)

See the jq manual for full details of supported expression syntax.

Sample query:

select package, "https://pypi.org/project/" || package || "/" as url,
jq(info, "{summary: .info.summary, author: .info.author, versions: .releases|keys|reverse}")
from packages

Try this query out in the interactive demo.
