InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
You could do that with PCGen, BahamutDragon's data sources for it (which cover a lot but not all of 3.5e) and custom output sheet matching your desired output. You'd have to do a json output sheet yourself, but here's an example for spell macros in roll20.
