BigQuery supports various output formats for exporting data, including AVRO, JSON, and CSV, all of which are commonly used for data transfer and storage in data processing environments.

AVRO is a row-oriented data serialization framework that allows for dynamic schema evolution, making it suitable for BigQuery's structured data. JSON, a lightweight data-interchange format, is widely used for representing complex data structures, making it flexible for various applications. CSV is a simple and widely recognized format for representing tabular data, making it easy to export and import between systems.

In contrast, DOCX is a proprietary document format created by Microsoft for word processing documents, which is not designed for data export in the same context as the other formats. This makes it unsuitable for BigQuery's data export capabilities, emphasizing that specific data serialization formats are designed to work seamlessly with data processing tools and frameworks. Thus, DOCX stands out as the format that BigQuery does not support for exporting data.
