JSQLFormatter review
A focused open-source formatter for Java teams that value parser-based SQL formatting.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
JSQLFormatter is an open-source SQL formatter, beautifier and pretty printer maintained by Manticore Projects. It is aimed at Java teams and developers working across Windows, macOS and Linux who need grammar-driven SQL parsing rather than simple text-based indentation. The project can format common SQL statements through a Java library, executable JAR, native binaries, or command-line usage. It supports Oracle, SQL Server, MySQL, MariaDB, PostgreSQL, H2, DuckDB, BigQuery, Redshift, Databricks and Snowflake dialects.
Its strongest area is configurable formatting depth. JSQLFormatter preserves comments and allows users to set indentation width, separator placement, and the casing of keywords, functions and objects. Output can be produced as plain text, ANSI, HTML or RTF, with syntax highlighting available for ANSI, HTML and RTF. The command-line interface handles files, folders and inline statements, while Java and native-code integration give development teams more than one way to add formatting to an existing workflow. These capabilities make it a practical fit for projects that need consistent SQL presentation across code and generated output.
JSQLFormatter is narrower than a full SQL development workflow: its published feature set emphasizes parsing, formatting, highlighting and integration APIs, while broader workflow and integration features are limited. That makes it a good choice for Java teams that want an open-source formatter with dialect coverage and direct programmatic access. Teams seeking a more extensive ecosystem around database development, automation or connected workflow management should consider a more integration-focused alternative. The project’s 2011 founding year also gives it an established history, while releases from 5.4 onward use Apache 2.0.
