sql-dialect-fmt

sql-dialect-fmt is an opinionated Rust formatter and editor toolchain for Snowflake SQL and Databricks SQL. It is built around a lossless lexer/parser pipeline: unsupported or malformed input is preserved, comments survive formatting, and repeated formatting is stable.

Use the playground to run the WebAssembly formatter in the browser, or install the CLI for local and CI usage.

cargo install sql-dialect-fmt --version 1.18.0 --locked
sql-dialect-fmt --check sql/**/*.sql
sql-dialect-fmt --write sql/**/*.sql
