Click a node to expand/collapse. Hover any value and click the copy icon to copy it. Everything runs in your browser — your data is never uploaded.
Explore TOML as an interactive collapsible tree, free. A TOML viewer renders a TOML config file as an interactive, collapsible tree of tables, arrays, and values so you can navigate nested configuration at a glance. This tool parses your TOML in the browser and lets you expand or collapse nodes, search, and copy any value on hover — entirely on your device.
It shows TOML tables, arrays of tables, and values as a navigable tree with search and copy-on-hover, making layered config easy to explore. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Tables and arrays of tables become expandable nodes, so nested config is easy to drill into.
Filter the tree to jump straight to the key or table you need.
Hover any node to copy its value or subtree to the clipboard.
Your TOML is parsed locally; nothing is uploaded, logged, or stored.
It parses TOML and shows it as an interactive tree of tables, arrays, and values, instead of raw text. That makes layered configuration files like Cargo.toml or pyproject.toml easier to read and navigate.
Yes. TOML has explicit types (strings, integers, floats, booleans, dates), and the tree reflects each value as parsed, so you can confirm a value is the type you expect.
Yes. TOML's [[array of tables]] syntax is shown as expandable repeated nodes, so you can navigate each entry individually.
No. It's parsed entirely in your browser — nothing is sent to a server.
A duplicate key, a missing quote, or an invalid date will fail to parse. Fix the syntax, then view it as a tree.
