About the JSON to SQL Converter
This JSON to SQL converter turns data files from JSON into SQL without installing software or uploading anything. It solves a common problem: JSON is hard for non-developers to read and does not open in Excel. Converting to SQL gives you a MySQL-ready SQL import script, ideal for importing data into MySQL, MariaDB, PostgreSQL or SQLite.
The file is parsed with well-tested open-source parsers (the browser's JSON and XML parsers, js-yaml and smol-toml) and written back out as valid SQL. Because everything happens on your own device, your data files are never uploaded, stored or seen by anyone else, which makes it safe for customer lists, salary sheets, GST data and API exports.
What to expect: nested objects are flattened into columns such as address.city, and the first list of records found in the file becomes the rows; invalid input is reported with the line of the problem so you can fix it.
How to use the JSON to SQL Converter
- Click "Choose files" or drag your JSON data files onto the box. You can add several at once.
- Set the table name for the CREATE TABLE and INSERT statements.
- Press "Convert to SQL". The conversion runs on your device and shows its progress.
- Download each SQL file, or use "Download all (ZIP)" when you converted several.
- Open the result in phpMyAdmin or MySQL Workbench to check it; your original JSON is never changed.
Tips & benchmarks
- Column types (INTEGER, REAL, TEXT) are detected from your data and every value is escaped safely.
- Lists of simple values are joined with semicolons, and lists of objects are kept as JSON text in one cell, so no information is lost.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the SQL to a website or government portal.
Frequently asked questions
How do I convert JSON to SQL?
Click "Choose files", select your JSON data files, adjust the options if you want, and press "Convert to SQL". The SQL downloads immediately; with several files you can download everything as one ZIP.
Is this JSON to SQL converter free and safe?
Yes. It is completely free, with no sign-up, no daily limit and no watermark. The conversion runs inside your browser, so your data files never leave your phone or computer and nothing is stored on News Appite's servers.
What happens to nested data?
Tables are flat, so nested objects become dotted column names (for example user.address.city). Lists of simple values are joined with semicolons and lists of objects are stored as JSON text in one cell.
Can I convert several JSON files at once?
Yes. Add as many JSON files as you like; they are converted one after another and you can download them individually or together as a ZIP.
Does it work on iPhone, Android and Mac?
Yes. The converter works in any modern browser, including Chrome, Safari, Edge and Firefox, on Android, iPhone, iPad, Windows, macOS and Linux. No app is needed.
What is the difference between JSON and SQL?
JSON (JavaScript Object Notation) is a structured data (text) best suited to APIs, web and mobile apps, configuration and MongoDB or Firebase data. SQL (SQL script (CREATE TABLE + INSERT)) is a database import script best suited to importing data into MySQL, MariaDB, PostgreSQL or SQLite.
Is there a file size limit?
There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.
How do I convert JSON to SQL in Python?
With pandas: df = pd.json_normalize(json.load(open('input.json'))), then df.to_sql('data', sqlite3.connect('output.db'), index=False). If you just need the file, this converter does it in the browser without writing any code.
JSON ko SQL kaise kare?
Is page par "Choose files" dabaiye, apni JSON file chuniye aur "Convert to SQL" par click kijiye. SQL file turant download ho jaati hai. Ye bilkul free hai, sign-up nahi chahiye, aur aapki file kisi server par upload nahi hoti.

What is a JSON file?
JSON is the data format of the modern web: almost every API, app configuration and NoSQL database speaks it. It represents objects, arrays, numbers and text in a compact, human-readable way.
What is a SQL file?
An SQL file is a script of database statements. The converter writes a CREATE TABLE statement followed by INSERT rows, so you can load the data into MySQL, MariaDB, PostgreSQL or SQLite in one step.
