This tool allows you to convert JSON (JavaScript Object Notation) data into the Apache Parquet format. Parquet is a columnar storage format available to any project in the Hadoop ecosystem, regardless of the choice of data processing framework, data model or programming language.
Parquet stores data by column rather than by row, which allows for better compression and faster queries when accessing specific fields.
Parquet enforces a schema, ensuring data consistency and type safety, unlike the flexible nature of JSON.
Apache Parquet is an open-source, column-oriented data file format designed for efficient data storage and retrieval. It provides high performance compression and encoding schemes.
Converting JSON to Parquet significantly reduces file size and improves query performance in big data processing frameworks like Spark, Hadoop, and AWS Athena.
Yes, our JSON to Parquet converter is completely free to use and processes your data securely in your browser.
Parquet supports nested structures, but for the best results with this tool, we recommend using a flat array of objects or ensuring a consistent schema.
