JSON to BigQuery Converter — Examples & 2025 Guide

Moving from JSON to BigQuery is a core workflow for analysts and data engineers working with semi-structured data. As more applications output logs and records in JSON, importing this data into Google BigQuery enables you to run scalable, lightning-fast analytics. But manual conversion — whether defining schemas or writing flattening SQL — can be error-prone and time-consuming.

AI2sql changes that: just describe your JSON and desired table schema, and get instant, production-ready SQL for every step. No coding knowledge or BigQuery expertise required.

Understanding JSON to BigQuery Conversion

• What is it? Transforming JSON data — often nested or complex — so it can be stored and queried efficiently in BigQuery tables.

• Why is it important? Many real-world datasets (from APIs, logs, IoT, etc.) are JSON-formatted. BigQuery’s native JSON support (and its SQL functions for parsing/nesting) makes it a preferred analytics destination.

• Challenges: Handling nested fields, type conversions, specifying schemas, and flattening arrays — all without introducing data loss.

How AI2sql Simplifies the Process

• Paste or upload your JSON sample.

• AI2sql auto-generates BigQuery DDL (table creation) and SQL for importing and parsing.

• Just copy, run in your Google Cloud Console, and analyze your data instantly.

• Trusted by 50,000+ developers, analysts, and enterprises globally.

Real-World Examples: JSON to BigQuery Conversion

Example 1: Create a BigQuery Table for JSON Records

CREATE TABLE project.dataset.users (
  id STRING,
  name STRING,
  profile STRUCT<age int64,="" email="" string="">,
  tags ARRAY<string>
);
</string></age>

Example 2: Load Inline JSON String and Parse

SELECT
  JSON_VALUE(json_column, '$.id') AS id,
  JSON_VALUE(json_column, '$.name') AS name,
  JSON_QUERY(json_column, '$.profile') AS profile_json
FROM UNNEST([
  '{"id":"u1","name":"John","profile":{"age":30,"email":"john@email.com"}}'
]) AS json_column;

Example 3: Flatten a Nested JSON Array to Rows

SELECT
  user.id,
  tag
FROM mydataset.myjson_table AS user,
UNNEST(user.tags) AS tag;
