TOML Viewer

beta

This free TOML viewer turns TOML into a collapsible tree, so tables, arrays of tables and nested keys are easy to follow. Open Cargo.toml, pyproject.toml, Hugo or Netlify configs, search across keys and values, and copy any path or value. Everything runs locally in your browser.

How to use TOML Viewer

  1. 1 Paste TOML or load a .toml file.
  2. 2 Expand tables and arrays of tables, or use Expand all.
  3. 3 Search to highlight matching keys and values.
  4. 4 Copy any value or path. Invalid TOML shows the line and column of the error.
