Integrating local files into BigQuery represents a vital aspect of expanding data accessibility and leveraging the platform’s analytical capabilities. This introduction will elucidate the process of seamlessly incorporating local files into BigQuery, elucidating the methods, considerations, and advantages inherent in this operation.

While BigQuery excels in processing vast datasets stored in Google Cloud Storage or other cloud-based repositories, there are scenarios where local files, residing within an organization’s infrastructure or on individual workstations, contain valuable data that warrants inclusion in analytical workflows.

The process of adding local files into BigQuery involves a few essential steps, such as preparing the data in a compatible format, uploading it to Google Cloud Storage, and then utilizing BigQuery’s native capabilities to ingest the data into its tables. Supported file formats include CSV, JSON, Avro, Parquet, and more, ensuring flexibility and compatibility with various data sources.
