Convert ODS to Avro

OpenDocument Spreadsheet (ODS) is an open standard file format for spreadsheets. It's part of the OpenDocument Format (ODF) family, developed by the Organization for the Advancement of Structured Information Standards (OASIS). Many office suites support it, including LibreOffice and Apache OpenOffice.

ODS files can have 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 main 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.

Avro is a row-based data serialization system developed within Apache's Hadoop project. It provides rich data structures and a compact, fast binary data format.

Technical Details

Avro uses JSON for defining data schemas, which are stored with the data. This enables schema evolution while maintaining compatibility. The data itself is stored in a compact binary format.

Advantages

• Compact binary serialization
• Schema definition included with the data
• Support for schema evolution
• Dynamic typing and code generation

Limitations

• Not human-readable without special tools
• Less widely supported than formats like JSON or CSV
• More complex to implement than simpler formats
• Less efficient for columnar queries than Parquet
