About this tool

CSV to SQL is a free converter that turns spreadsheet data into ready-to-run SQL. It parses your CSV, auto-detects each column's data type, maps types to your target dialect, and generates a CREATE TABLE statement plus INSERT statements.

Input
Pasted CSV text or an uploaded .csv file (comma-delimited, quoted fields supported)
Output
CREATE TABLE statement plus INSERT statements (single-row or compact multi-row); column names with spaces or special characters are quoted automatically
Dialects
Standard SQL, PostgreSQL, MySQL, SQLite
Type detection
Automatic per column: INTEGER, DECIMAL, BOOLEAN, DATE, TIMESTAMP, or TEXT — mapped per dialect (e.g., MySQL TINYINT(1) for booleans, PostgreSQL NUMERIC for decimals, DATETIME for timestamps; SQLite keeps dates as ISO-8601 TEXT)
Options
Custom table name (or derived from the uploaded filename), multi-row INSERT
Signup
Not required
Processing
Entirely in your browser — CSV data is never uploaded for processing
Difference
Column types and dates are auto-detected per dialect — no manual schema typing like generic converters require
Price
Free

Limitations

  • Supports comma-delimited CSV only (no semicolon or tab delimiters).
  • Requires a header row plus at least one data row.
  • Does not connect to a database — the generated SQL is for copy-paste use.

Each column is auto-detected as INTEGER, DECIMAL, BOOLEAN, DATE, TIMESTAMP, or TEXT and mapped to your target dialect (PostgreSQL, MySQL, SQLite, or standard SQL).
