Format Details
CSV
CSV (Comma-Separated Values) is a plain-text tabular data format that uses commas to delimit column values and line breaks to separate rows. It is one of the most universally supported data interchange formats, readable by any spreadsheet application, database, or programming language. CSV is ideal for exporting and importing data between different systems due to its simplicity, human readability, and near-universal compatibility.
Parquet
Apache Parquet is an open-source binary columnar storage format designed for efficient analytical data processing across the big data ecosystem. Its columnar layout enables excellent compression ratios and fast query execution when only a subset of columns is needed. Parquet is the de facto standard format for data lakes and is natively supported by Apache Spark, Hadoop, Presto, Snowflake, and most modern data processing platforms.
