How to Convert JSON to CSV or SQL Online
JSON is great for APIs and configuration, while CSV and SQL are perfect for analysis and databases. This guide shows how to use the WebSauda JSON⇄CSV⇄SQL converter to move between these formats without writing custom scripts.
When do you need JSON → CSV or JSON → SQL?
You might want to convert JSON when:
- You pulled data from an API and want to analyse it in Excel.
- You received a JSON export and need to import it into a relational database.
- You are preparing demo data for a project or documentation.
- You want a quick way to inspect nested objects and arrays.
Convert JSON to CSV using WebSauda
- Open the JSON⇄CSV⇄SQL converter.
- Paste your JSON into the input box or upload a file if supported.
- Choose the JSON → CSV mode and preview the flattened data.
- Export or copy the resulting CSV and open it in Excel, Google Sheets or any other spreadsheet tool.
Generate SQL INSERT statements from JSON
For quick database seeding, you can convert JSON objects into SQL INSERT statements.
- In the same WebSauda converter, switch to the JSON → SQL mode.
- Provide a table name and review the detected columns.
- Generate the SQL script and run it in PostgreSQL, MySQL, SQLite or your preferred database.
Best practices for clean conversions
- Keep your JSON consistently structured; avoid mixing shapes in one array.
- Normalise nested objects before converting, or flatten them into dotted paths.
- Review column names and data types before running the generated SQL on production.
