Frequently asked questions
Is my code sent to a server?
No. The formatters and minifiers (Prettier, sql-formatter, Terser, and CSSO) load into the page and run on your device, so your code stays in your browser.
Which SQL dialects are supported?
Standard SQL, MySQL, MariaDB, PostgreSQL, SQLite, SQL Server (T-SQL), Oracle PL/SQL, BigQuery, Snowflake, Redshift, Spark SQL, Hive, Trino/Presto, DuckDB, ClickHouse, and IBM Db2. You can also set Keyword case to UPPER, lower, or As is.
Why is Minify greyed out for TypeScript or Markdown?
TypeScript needs compiling to JavaScript before it can be minified, and Markdown has nothing to minify, so those languages are formatted instead.
Does minifying JavaScript rename my variables?
Only if Shorten variable names is on. It renames local variables and functions; global names stay the same. Keep license comments preserves /*! and @license comments.
Where does it show syntax errors?
Below the editors, with the line and column when the parser reports them. The faulty line is also highlighted in the input.
Are my settings remembered?
Yes. Mode, language, and options are saved in this browser's local storage. Your code is not saved.
