Convert ODS to Parquet

OpenDocument Spreadsheet (ODS) is an open standard file format for spreadsheets that is part of the OpenDocument Format (ODF) family. It was developed by the Organization for the Advancement of Structured Information Standards (OASIS) and is widely supported by various office suites, including LibreOffice and Apache OpenOffice.

ODS files can contain multiple sheets, and each sheet can contain multiple rows and columns of data. The format supports a wide range of features including formulas, styles, charts, and macros.

One of the key advantages of ODS is its open nature, which ensures long-term accessibility and interoperability. It uses a compressed XML format, making it both efficient in storage and easy to process programmatically.

Apache Parquet is a columnar storage format optimized for use with big data processing frameworks. It offers efficient data compression and encoding schemes, which leads to significant storage savings and improved read performance.

Parquet is designed to support complex nested data structures and enables efficient querying and manipulation of specific columns without reading the entire dataset.

Compression

Parquet supports various compression algorithms such as Snappy, Gzip, and LZO. These compression techniques help in reducing the storage space and improving the performance of data processing tasks.
