Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How to convert a massive JSON into CSV
This tool was built for this purpose https://github.com/kindly/flatterer

Show HN: Flatterer Lite, A Rust WASM JSON to tabular converter, for nested data
I have been working on this Rust based JSON flattener (https://github.com/kindly/flatterer) to XLSX/CSV/SQLITE/PARQUET/POSTGRES for about 2 years. I finally made a WASM based one for CSV/XLSX which is really easy to play with. You can use it via a url (if the data has CORS headers), for example https://lite.flatterer.dev?url=https%3A%2F%2Fdummyjson.com%2....
The main difference with other converters/flatteners is that for one-to-many relationships (lists of objects in JSON) it produces a multi table output with keys to help join the tables together. Essentially produces a relational schema, along with some type information, of the JSON provided. For simple non-nested JSON it works too, but is a bit overkill.
Its all opensource and free, and I think that it will become more and more useful as JSON/Graphql APIs proliferate.

Create table from JSON
flatterer is the easiest option and will do this for you. It will also load the data into a sqlite or postgres database for you.
-
Robust Rust Library for Converting JSON Objects into CSV Rows
I have also written something similar but higher level flatterer which is python but is a binding to libflatterer. Its main difference is when there is a list of objects it treats it a one to many and creates a separate CSV file.

Flatten a massive json file
flatterer (github) is designed for this.
-
Simple GUI tool to query JSON or CSV databases [I have no coding skills]
This looks great and using duckdb as a backend us a great choice. For JSON I suggest using flatterer https://flatterer.opendata.coop/ . Which will convert most JSON into CSV/Parquet with very little technical knowledge.
-
Rust for Data Engineering
My project flatterer (used for flattening JSON into tables) also is mainly a python cli/libarary but is written in Rust for speed/memory efficiency and better concurrency.
-
JSON Processing
I have been working on a similar tool for the last while called flatterer (github). It has a similar aim and works with most kinds of JSON well (but not very well with top level objects like yours).
-
Stream processing - Nested JSON to Parquet
You could try Option B with flatterer https://flatterer.opendata.coop/ which purpose is to convert nested JSON into other formats without a schema upfront including parquet.
