Private SQL tools for deliberate dialect work

Format, validate, parameterize, inspect, compare, and convert bounded SQL without uploads, database connections, or execution.

MySQL, PostgreSQL, SQLite, and Transact-SQL are always selected explicitly.

Choose a precise SQL job

Each route owns a different input, output, or safety contract. Syntax-only validation and static analysis never claim database runtime behavior.

SQL FormatterValidate the selected dialect, then apply readable whitespace and keyword casing without executing the statement.Open tool
SQL Syntax ValidatorParse one explicit SQL dialect and report syntax status, statement count, and statement types.Open tool
SQL ParameterizerReplace supported scalar literals in parsed DML with dialect-specific placeholders and return a reviewable binding map.Open tool
SQL Query AnalyzerSummarize syntax-tree facts for the selected dialect without claiming runtime plan or cost information.Open tool
SQL Query ComparatorParse two statements under one dialect and report bounded structural additions, removals, and changes.Open tool
SQL DDL to JSONExtract tables, ordinary columns, primary-key flags, nullability, and declared foreign keys from supported DDL.Open tool
SQL Schema ComparatorExtract the same narrow schema model from two DDL inputs and compare their tables, columns, and foreign keys.Open tool
SQL DDL to Mermaid ERDGenerate Mermaid erDiagram text from the narrow CREATE TABLE model without querying a catalog.Open tool
SQL INSERT to JSONMap explicit INSERT columns to supported scalar VALUES rows without evaluating functions or expressions.Open tool
JSON to SQL INSERTSerialize uniform flat JSON rows into a dialect-quoted literal INSERT and validate the generated SQL locally.Open tool

Start with the SQL formatter

Choose the actual target dialect, then format locally or open a dedicated route for a narrower job.

Format SQL

Inputs stay in this browser tab. Parser-heavy work uses a tighter 256 KiB safety cap.

Formatted SQL

No result is placed in a URL, account, API, or remote log.

A local SQL review workspace

Queries and schemas can reveal private application structure. Source and results stay inside the active browser tab.

These tools never execute SQL, connect to a database, resolve files or URLs, inspect catalogs, or infer the dialect.

Converters use narrow owned subsets and reject unsupported parser shapes instead of silently losing SQL meaning.
