Frequently asked questions

How do I format a SQL query online?

Paste your SQL, choose an indent size of 2 spaces, 4 spaces or tabs, and click format. Keywords such as SELECT, FROM, WHERE and JOIN are set in uppercase and major clauses are placed on separate lines with nested parentheses indented.

Does the SQL formatter change what my query does?

No, formatting only changes whitespace, line breaks and the case of recognised keywords. Table names, column names and string values are kept as written. Still, review the output before running it, because a formatter is not a SQL parser and does not validate your query.

Which SQL dialects are supported?

It uses a general-purpose keyword-based approach rather than a dialect-specific parser, so it works well for common SELECT, INSERT, UPDATE, DELETE and CREATE TABLE statements in MySQL, PostgreSQL, SQL Server and others. Unusual vendor syntax may be laid out imperfectly.

Why are my SQL keywords in uppercase?

Formatting converts recognised keywords to uppercase, which is a common convention that makes them stand out from table and column names. SQL keywords are case-insensitive, so this does not affect how the query runs.

Does formatting SQL make it run faster?

No. Whitespace and line breaks are ignored by the database, so a formatted query has the same execution plan and speed as a minified one. Formatting only makes a query easier to read, review and debug. To speed a query up you need better indexes or a rewritten query.

How do I make a long SQL query easier to read?

Format it so every clause starts on its own line, then use a consistent indent so AND, OR and ON conditions are visibly nested under their parent clause. Formatting is also useful before code review or when you paste a query into documentation.

Is my data shared when using the SQL Formatter?

No. Toolskyt operates under a zero-server policy. All calculations, data formatting, and file exports are executed locally on your machine.

Do I need to sign up or pay to use the SQL Formatter?

No, this tool is 100% free. There are no limits, sign-ups, subscriptions, or hidden charges required.

Is it safe to paste API tokens or private JSON data here?

Yes, absolutely. The tool executes 100% inside your local browser memory space. No inputs are sent to any servers.
