verified Jul 3, 2026

bigquery-schema-generator is a Python library that generates BigQuery schemas from newline-delimited JSON or CSV data. Unlike BigQuery's native auto-detection which typically samples only the first 500 records, this tool processes all input data to create a more comprehensive and accurate schema. Currently at version 1.6.1, the library maintains an active release cadence, providing regular updates and bug fixes.
