SQL (Structured Query Language) is the standard language for querying and managing relational databases such as PostgreSQL, MySQL, and SQL Server.
SQL Editor is an online tool that helps you edit SQL.
It lets you edit SQL with inline validation and a preview so small fixes do not require a full IDE.

SQL Editor is comfortable with files up to ~10 MB. Beyond that, Monaco's tokenizer starts to slow down on low-end devices — split the file or use a native editor for multi-MB single files.
Yes. SQL Editor exposes copy-to-clipboard and file download, plus round-trip conversion to the related formats (e.g., JSON editor can export to YAML or XML) so you don't need to chain three tools.
Yes. SQL Editor follows the site's theme, which respects your OS "prefers-color-scheme" setting. Toggle manually with the theme switch in the header.
SQL Editor doesn't upload drafts anywhere — your content stays local. To share, export the file or copy the content into a gist, pastebin, or your own document store.
Yes. SQL Editor uses the Monaco editor (the same engine behind VS Code), so you get real syntax highlighting, bracket matching, and folding — not a plain textarea.
