Accepts json
JSON
Java Script Object Notation (JSON) is a format that was designed for use with the Javascript Programming Language.
JSON files do not have a schema or required columns. Each row can have different field names and types. This can
make JSON files difficult to analyze.
Parquet
Apache Parquet (.parquet) is a format that was designed for storing tabular data on disk. It was designed based on the format used in Google's Dremel paper (Dremel later became Big Query).
Parquet files store data in a binary format, which means that they can be efficiently read by computers but are difficult for people to read.
Parquet files have a schema, so means that every value in a column must have the same type. The schema makes Parquet files easier to analyse than CSV files and also helps them to have better compression so they are smaller on disk.

How to Convert JSON to Parquet in Python
We can convert JSON to Parquet in Python using Pandas or DuckDB
How to Convert JSON to Parquet using Pandas
First, we need to install pandas
pip install pandasThen we can load the JSON file into a dataframe
df = pd.read_json('path/to/file.json')Finally, we can export the dataframe to the Parquet format
df.to_parquet('path/to/file.parquet', index=False)How to Convert JSON to Parquet using DuckDB
First, we need to install duckdb for Python
pip install duckdbThe following DuckDB query will read a JSON file and output a Parquet file
duckdb.sql("""COPY (select * from 'path/to/file.json') TO 'path/to/file.parquet' (FORMAT 'parquet')""")Tabular Data Converters
