Indented List to ASCII Tree

Turn a plain indented outline into a clean, copy-pasteable directory tree — the kind you see at the top of a well-written README.

How it works. Paste any hierarchical list that uses 2-space, 4-space or Tab indentation. Markdown bullet prefixes (-, *, +, 1.) are optional and stripped automatically; blank lines are ignored. The parser auto-detects the most common indent unit, or you can force one. The result is rendered with proper tree connectors.

Two output styles.

• Unicode Box Drawing (├── └── │) — the modern default, looks great on GitHub, Discord, VS Code and most terminals.
• Classic ASCII (|---- |`) — no Unicode at all, safe for plain-text emails, old terminals, and ANSI-only environments.

Three difficulty toggles.

• Full guide lines — draw the vertical │ line all the way down so parents line up visually; turn off for a more compact tree.
• Bracket leaf nodes — wrap files in [], e.g. docs/[api.md], the convention used by tree and many docs.
• Trim trailing spaces — strips the spaces left behind after the last connector, for cleaner diffs and smaller pastes.

Why use this instead of the tree CLI. tree only works on real folders on your disk. This tool works on any indented text — an outline, a brainstorm, a Markdown spec, a Notion export — and lets you pick the exact style without leaving the browser.
