Excel to CREATE TABLE Generator (SQL Server / MySQL / PostgreSQL)
Upload Excel headers and sample rows to generate CREATE TABLE DDL with inferred column types for SQL Server, MySQL, or PostgreSQL.
How it works
Open Excel to SQL, map columns, choose a database dialect, enable CREATE TABLE, then generate. Types are inferred from up to 200 non-empty sample cells per column.
Supported dialects
SQL Server (NVARCHAR/INT/DECIMAL/DATE/DATETIME2/BIT), MySQL (VARCHAR/TEXT/INT/DECIMAL/DATE/DATETIME), PostgreSQL (TEXT/INTEGER/NUMERIC/DATE/TIMESTAMP/BOOLEAN).
Tips for clean DDL
Use clear header names, keep one type per column, and remove blank rows before generating.
Next step
After DDL, generate INSERT scripts in the same tool or load data with your ETL pipeline.

FAQ
Is CREATE TABLE free?
Yes. Use the Excel to SQL tool and check Include CREATE TABLE.
Will types always be perfect?
Inference is heuristic. Review NVARCHAR/VARCHAR lengths and numeric precision before production.
Which page should I open?
Use the main Excel to SQL tool, or dialect landing pages for SQL Server, MySQL, and PostgreSQL.
