Frequently Asked Questions
Is it safe to format proprietary JSON or XML code here?
Yes, 100% safe. The formatting and linting operations happen locally. No network requests are sent with your code, keeping your intellectual property completely secure.
How does the JWT Decoder handle secure tokens?
The decoder splits the JSON Web Token structure (header, payload, signature) using client-side base64 url-decoding. No keys or tokens are stored or sent anywhere.
Does the SQL Formatter support multiple dialects?
Yes, you can format queries tailored for Standard SQL, PostgreSQL, MySQL, and Microsoft SQL Server (T-SQL) with customized indentation spacing.
