JSON to BigQuery is a conversion tool that generates Google BigQuery-compatible schema definitions and newline-delimited JSON (NDJSON) for data loading. It maps JSON types to BigQuery's data types, including support for nested and repeated fields.

Paste your JSON data. The tool will generate the BigQuery table schema (in JSON format) and the NDJSON data file content. You can then use these to create and load tables in the Google Cloud Console or via the bq CLI.

BigQuery is a powerful data warehouse, but loading data requires specific schema definitions and data formats. This tool automates the creation of these schemas from your sample JSON, significantly reducing the setup time for new datasets.

Inconsistent types

Fix: BigQuery requires a fixed schema; ensure all objects in your JSON array have consistent types for the same fields.

Reserved keywords

Fix: Avoid using BigQuery reserved keywords as field names in your JSON.
