Product Documentation

This is the practical user manual: how to get the most out of FormatterHub without digging through menus. Every tool follows the same basic shape -- paste or upload your input, pick an operation, copy or download the result.

Formatting

Open any formatter (say, the JSON Formatter) and paste your content -- it formats automatically. Switch between Format, Minify and Validate with the toolbar buttons, or Ctrl+Enter to re-run the last action.

The two-pane editor -- input on the left, formatted output on the right, with line numbers on both.

Validation & fixing

When validation fails, we show the exact failing line and column, with a caret pointing at the problem and a plain-language hint. For common mistakes -- trailing commas, single quotes, unescaped ampersands -- the one-click Fix button repairs and re-formats in place.

Errors show the failing line, a caret under the column, and a suggested fix.

Tree view, search and export

JSON and XML support a collapsible tree view with expand/collapse all. Use in-editor search and go-to-line to navigate a large document quickly, then copy to clipboard or download the result.

Note for maintainers: the screenshot placeholders above should be swapped for real captures once the app is deployed.
