Database Documentation
Quickly generate clean documentation for existing database schemas. Perfect for creating API docs or technical specifications that show table structures clearly.
Code Review Process
Analyze database migration scripts during code reviews. Quickly understand what fields are being added, modified, or have specific constraints applied.
Legacy Database Analysis
Understand old database structures when working with legacy systems. Parse existing CREATE statements to get a clear view of table relationships and constraints.
Learning Database Design
Educational tool for students and developers learning SQL. Visualize how different data types, constraints, and relationships are defined in CREATE TABLE statements.
API Development Planning
Plan REST API endpoints by understanding database table structures. Identify required fields, data types, and constraints before building CRUD operations.
Database Migration Verification

Frequently Asked Questions
What is SQL Fields Viewer?
SQL Fields Viewer is a free online tool that parses SQL CREATE TABLE statements and displays table structure information in a clean, organized format. It extracts field names, data types, constraints, default values, and relationships, making it easy to understand database schemas at a glance.
Which SQL database systems are supported?
The tool supports CREATE TABLE syntax from major database systems including MySQL, PostgreSQL, SQL Server, SQLite, Oracle, and MariaDB. It handles common data types, constraints (PRIMARY KEY, FOREIGN KEY, UNIQUE, NOT NULL), and most standard SQL features across these platforms.
Is SQL Fields Viewer completely free?
Yes, SQL Fields Viewer is 100% free to use with no registration required, no usage limits, and no hidden fees. You can parse unlimited SQL statements and export results in multiple formats without any restrictions.
Can I analyze multiple tables simultaneously?
Absolutely! You can paste multiple CREATE TABLE statements in the input area, and the tool will parse each table separately, displaying all table structures in organized sections with clear separation between different tables.
What export formats are available?
You can export parsed table structures in three formats: JSON (for programmatic use), CSV (for spreadsheet applications), and Markdown (for documentation). This makes it easy to integrate the results into your workflow or share with team members.
Is my SQL data secure and private?
Yes, your data is completely secure. All SQL parsing is performed entirely in your browser using client-side JavaScript. Your SQL statements are never transmitted to our servers, stored, or logged anywhere. This ensures complete privacy and security for sensitive database information.
How accurate is the SQL parsing?
The parser is designed to handle standard SQL CREATE TABLE syntax accurately, including complex constraints, foreign keys, and various data types. While it covers most common use cases, some highly specialized or vendor-specific syntax variations might require manual review.
Can I use this tool for database migrations?
Yes, SQL Fields Viewer is excellent for analyzing migration scripts. You can paste your CREATE TABLE statements to verify field definitions, constraints, and relationships before running migrations, helping prevent deployment issues and ensuring schema accuracy.
