Why Convert CSV to SQLite?
A CSV is data you can look at; a SQLite database is data you can query. This tool converts a CSV into a real .sqlite file — your header row becomes column names, column types (INTEGER, REAL, TEXT) are inferred from the data, and every row is inserted into a table named after your file.
It runs actual SQLite, compiled to WebAssembly, in your browser tab — the same engine used by the sqlite3 command line. The resulting file opens in any SQLite tool, ORM, or application.
Nothing is uploaded: your data goes from CSV to database without leaving your device.
Key Features
About CSV and SQLite Formats
CSV (CSV)
CSV (Comma-Separated Values) is a simple text format for tabular data. Universally compatible with spreadsheets and databases.
SQLite (SQLite Database)
SQLite is a self-contained, serverless database engine. The database is stored in a single file, making it portable and easy to use.
Common Use Cases
- Turn a large CSV export into something you can query with SQL
- Prepare seed data for an app that reads SQLite
- Convert spreadsheet data for analysis in tools that speak SQLite
- Bundle a dataset as a single portable .sqlite file
Frequently Asked Questions
How are column types decided?
Each column is scanned: if every non-empty value is a whole number it becomes INTEGER, if every value is numeric it becomes REAL, otherwise TEXT. Empty cells are stored as NULL.
What are the table and column names?
The table is named after your file (sanitized), and columns come from the CSV header row with special characters replaced by underscores — so "Order Date" becomes Order_Date.
Can I convert the database back to CSV later?
Yes — the SQLite to CSV tool on this site does the reverse, and SQLite to JSON exports the same data as JSON.
Is there a size limit?
Processing happens in your browser’s memory, so it depends on your device — typical CSVs convert instantly; very large files (hundreds of MB) depend on your hardware.
