HTML Table to SQL Converter
Transform raw HTML <table> markup and scraped web tables into clean SQL schemas and multi-row INSERT queries in seconds.
At a glance
HTML Table to SQL Converter is a free, client-side tool that converts HTML table markup into SQL CREATE TABLE DDL and INSERT statements with smart column type inference across PostgreSQL, MySQL, and SQLite. It automatically identifies integers, decimals, booleans, dates, and text columns. Everything runs locally in your browser — nothing is uploaded and no sign-up is needed.

How to Convert HTML Tables into SQL Schemas & Seed Queries
HTML tables are the de facto format for displaying structured tabular information across the web, including financial statements, analytics dashboards, Wikipedia datasets, and scraped directory reports. Converting raw HTML markup into relational database tables traditionally requires writing custom scraping scripts or tedious regex manipulation.
The HTML Table to SQL Converter runs 100% in your local web browser, extracting column headers and data rows directly from HTML table blocks or raw <tr> rows. It intelligently inspects each column's data to infer optimal SQL types (such as INTEGER, NUMERIC, BOOLEAN, DATE, or VARCHAR), generates production-ready CREATE TABLE DDL schemas, and outputs clean batch INSERT INTO statements for PostgreSQL, MySQL / MariaDB, SQLite, and ANSI SQL.
Smart Type Inference
Automatically inspects cell values to determine whether a column represents whole numbers, monetary decimals, booleans, ISO dates, or text strings.
Multi-Dialect Code Generation
Generates idiomatic SQL for PostgreSQL (double-quoted identifiers, SERIAL primary keys), MySQL (backticks, AUTO_INCREMENT), and SQLite.
Cell Sanitization & Escaping
Strips nested tags (such as <a>, <span>, <b>), decodes HTML entities, and doubles single quotes (O'Reilly to O''Reilly).
Step-by-Step Conversion Workflow
- Paste HTML Markup or Upload File: Copy the
<table>...</table>block from your browser's Developer Tools or paste raw table markup into the input editor. - Configure Destination Schema: Set your target SQL table name, pick your database engine (PostgreSQL, MySQL, SQLite, ANSI SQL), and toggle primary keys or identifier quoting.
- Select Table Index (if multi-table): If your input contains multiple tables, choose which table to convert using the Table Index dropdown.
- Copy or Download SQL: Copy the combined DDL and INSERT statements to your clipboard or download them as a ready-to-run
.sqlmigration script.
Frequently Asked Questions
How does column type inference determine database types?
The converter evaluates every value in a column across all rows. If all values are whole numbers, it selects INTEGER; if decimal numbers are found, it uses NUMERIC/DECIMAL; for true/false or yes/no values, it uses BOOLEAN; for ISO dates, it selects DATE; otherwise, it falls back to VARCHAR or TEXT.
Can I convert raw table rows (<tr>) without a parent <table> tag?
Yes. The engine seamlessly parses raw <tr> and <td> snippets even if the outer <table> or <tbody> wrapper tags are omitted.
How are single quotes in string values handled?
All string values are sanitized using standard SQL escaping where single quotes are doubled (e.g., 'O''Reilly') to ensure queries execute cleanly without syntax errors.
Can I generate INSERT statements without CREATE TABLE?
Yes. Simply uncheck 'CREATE TABLE DDL' in the toolbar to generate only INSERT INTO seed statements for an existing table.
Are my HTML documents or table records sent to any remote server?
No. The entire conversion and schema inference process runs 100% client-side in your local browser sandbox. Zero data is ever sent across the network.
