Simplenote Export to Markdown

What this tool does

Simplenote lets you export all of your notes as a single JSON file (simplenote.json). That file is great for backup but useless for reading, and most note apps — Obsidian, Joplin, VS Code, a plain folder of files — expect one Markdown file per note. This tool does that conversion, entirely in your browser: paste the JSON and get a bundle of clean .md files, one per note, each with a title heading, its tags, and its dates.

Nothing is uploaded. The conversion runs locally in WebAssembly, works offline once the page has loaded, and needs no sign-up.

What you get

Each note becomes one Markdown file in the output, preceded by an ==== filename.md ==== header so you can see — and split out — every file:

• A # Title heading taken from the note's title (or its first line).
• Its tags, either as a YAML tags: list or as #hashtags.
• Its created / updated dates, in the frontmatter.
• The note's pinned / markdown flags, when set.

Options

Supported export formats

• Modern Simplenote export — a JSON object with activeNotes and trashedNotes arrays. Each note carries content, tags, creationDate / lastModified, and pinned.
• Legacy Simplenote export — a JSON array of note objects with key, content, tags, and numeric createdate / modifydate epoch times (converted to real dates for you).
• Evernote-style JSON — a JSON array where each note has an explicit title plus content / text / body, tags, and created / updated.

Example

Paste this Simplenote export:

{ "activeNotes": [
  { "id": "abc-123", "content": "Grocery List\nMilk\nEggs",
    "tags": ["home", "shopping list"],
    "creationDate": "2026-01-15T09:30:00.000Z",
    "lastModified": "2026-01-16T10:00:00.000Z", "pinned": true } ] }

…with date-title filenames and frontmatter metadata, and you get:

==== 2026-01-15-grocery-list.md ====
