JSON to SQL Converter
Convert your JSON data into SQL INSERT statements for database operations.
About the JSON to SQL Converter Tool
We created this tool for developers and data analysts who need an easy way to move data from JSON format into a relational database. It takes a JSON array of objects and quickly generates SQL `INSERT` statements. You can even have it create the `CREATE TABLE` statement for you, complete with its best guess at the right data types for your columns.
How to Use the Tool
- Paste your JSON array into the input box on the left, or upload a JSON file.
- In the "Options" section, you can set your table name and choose the specific SQL dialect you need.
- Use the checkboxes to decide if you want to include a `CREATE TABLE` statement.
- The tool instantly generates the SQL code on the right, which you can copy or download.
Frequently Asked Questions
Why would I convert JSON to SQL?
JSON is a popular format for APIs and web applications, but many businesses store their data in traditional SQL databases. This tool bridges that gap, making it easy to take JSON data you have received and import it into a database like MySQL or PostgreSQL for storage and analysis.
What format does my JSON need to be in?
The tool expects your data to be a JSON array of objects. Each object in the array represents a row of data, and the keys in the objects are used as the column names. The tool uses the keys from the very first object to determine the headers for all the rows.
How does the tool guess the data types for the CREATE TABLE statement?
When you ask for a `CREATE TABLE` statement, our tool looks at the first 100 records in your JSON data. It checks each column to see if the data looks like integers, numbers with decimals, or text. Based on what it finds, it makes an educated guess for the most suitable SQL data type, like `INT`, `DECIMAL`, or `VARCHAR`.
What is the "Batch Size" option for?
Instead of creating a separate `INSERT` statement for every single row, which can be slow for large amounts of data, the batch size option groups multiple rows into a single `INSERT` statement. This is much more efficient and can significantly speed up the time it takes to import data into your database.
Is the data I enter private and secure?
Yes, absolutely. This tool is built with JavaScript and runs entirely in your web browser. All the data processing and SQL generation happens on your own computer. Your JSON data is never sent to our servers, so it remains completely private.
