Why convert JSON to SQLITE3?
JSON is a data-exchange format suited to APIs but poor for querying. Once your data is in .sqlite3, you can run SQL queries, join tables, and filter rows without running a database server. SQLite stores everything in a single portable .db file that is easy to move, back up, and share.
How to convert JSON to SQLITE3
sqlite-utils OPEN-SOURCE
Install via pip install sqlite-utils, then run sqlite-utils insert mydata.db tablename file.json to create a SQLite database and load the JSON array as rows.
DB Browser for SQLite FREE
Create a new database file, then use File > Import > Table from JSON file to select your .json and map it to a table.
Python FREE
Use the built-in json and sqlite3 modules to load the JSON array and insert each object as a row, giving full control over column types and data structure.
About these formats
.JSON
JavaScript Object Notation file
A JSON file is a plain-text data file in JavaScript Object Notation format, used by web APIs, app configurations, and data exports. Any text editor opens it - Notepad on Windows, TextEdit…

.SQLITE3
SQLite 3 Database
A .sqlite3 file is a complete relational database stored in one binary file by SQLite - the same format as .sqlite and .db. It holds structured tables of data, not a readable document. Open…

- JSON must be an array of objects at the top level for a clean import; a single object, deeply nested structure, or JSON Lines file each require different handling.
- All values are stored as TEXT by default in sqlite-utils unless you pass
--detect-types; specify types explicitly if you need integer arithmetic. - SQLite stores everything in a single
.dbor.sqlite3file - no server is needed - making it easy to move and share the resulting database.
Frequently asked questions
Does this work with nested JSON?
--flatten flag to flatten one level of nesting into extra columns; deeply nested structures need a custom Python script.
