Logseq To Obsidian

Logseq to Obsidian Migration

Migrate Logseq graphs to clean Obsidian vaults while preserving content and structure.

Workflow

Step 1: Locate and Analyze the Graph

First, find the Logseq graph. Check current directory for pages/ and journals/ folders:

ls -la

If not in a Logseq graph, ask the user for the path.

Run the analysis script to detect patterns:

python3 scripts/analyze_graph.py /path/to/logseq/graph --json

This outputs a JSON report of detected features (admonitions, block refs, properties, namespaces, etc.).

Step 2: Check for Existing Config

Check if a config file already exists:

cat /path/to/logseq/graph/.logseq-to-obsidian/config.json 2>/dev/null || echo "No config found"

If config exists, ask: "Found existing migration config. Use these settings, or reconfigure?"

If using existing config, skip to Step 4.

Step 3: Gather Preferences and Write Config

Based on analysis, ask ONLY the questions that matter. Skip questions for features not detected.

IMPORTANT: The AskUserQuestion tool has a maximum of 4 questions per call. If you have more than 4 questions, ask in multiple rounds. Never skip questions.

Round 1 — Core questions (always ask)

1. Output folder location (default: ../obsidian-vault)
2. "Keep all bullets or flatten top-level to paragraphs?" (recommend flatten for document-like notes)
3. "Place pages in vault root or in a pages/ subfolder?" (recommend root — cleaner structure)
4. "Organize pages by parent?" (recommend yes — pages linked from only one parent get nested, reducing sidebar clutter)

Round 2 — Conditional questions (ask if detected, in a second AskUserQuestion call)

• Namespaces found → "Convert Parent/Child pages to folder hierarchy?"
• Block references found → "Flag block refs for manual fix, or remove?"

If no conditional questions are needed, skip Round 2.

Automatic defaults (never ask)

• Journals → Daily/ folder, YYYY-MM-DD.md format
• Properties → YAML frontmatter
• Admonitions → Obsidian callouts
• collapsed:: true → Remove
• logseq.order-list-type:: number → Standard numbered lists
• Image sizing {:height X, :width Y} → Remove

After gathering preferences, create the config directory and write the config file:

mkdir -p /path/to/logseq/graph/.logseq-to-obsidian

Then use the Write tool to create /path/to/logseq/graph/.logseq-to-obsidian/config.json:

{
  "version": 1,
  "source": "/absolute/path/to/logseq/graph",
  "output": "/absolute/path/to/obsidian/vault",
  "preferences": {
    "flattenTopLevel": false,
    "namespacesToFolders": false,
    "organizeByParent": false,
    "pagesInRoot": false,
    "blockRefs": "flag",
    "journalsFolder": "Daily"
  }
}

Important: Use absolute paths in the config file.

Step 4: Run Dry-Run Migration

Always run dry-run first using the config:

python3 scripts/migrate.py --config /path/to/logseq/graph/.logseq-to-obsidian/config.json --dry-run

Show the user:

• Number of files to process
• Sample of 2-3 converted files (before/after)
• Any warnings or issues detected

Step 5: Execute Migration

After user confirms:

python3 scripts/migrate.py --config /path/to/logseq/graph/.logseq-to-obsidian/config.json

The script:

1. Creates output directory structure
2. Processes all .md files in pages/ and journals/
3. Copies assets/ folder
4. Reports progress and any issues

Step 6: Post-Migration Guidance

After migration, provide:

1. Recommended Obsidian plugins for Logseq refugees:

   • Calendar (visual calendar sidebar)
   • Periodic Notes (daily/weekly notes)
   • Outliner (folding, move items up/down)
   • Dataview (query notes, replaces Logseq queries)

2. Manual fixes needed (if any):

   • Block references flagged with <!-- TODO: -->
   • Logseq queries that need Dataview conversion

3. Quick start: "Open Obsidian → Open folder as vault → Select the output folder"

Config File Reference

The config file is stored at .logseq-to-obsidian/config.json in the Logseq graph directory.

Schema

{
  "version": 1,
  "source": "/absolute/path/to/logseq/graph",
  "output": "/absolute/path/to/obsidian/vault",
  "preferences": {
    "flattenTopLevel": false,
    "namespacesToFolders": false,
    "organizeByParent": false,
    "pagesInRoot": false,
    "blockRefs": "flag",
    "journalsFolder": "Daily"
  }
}

Fields

Re-running Migrations

Users can edit the config file directly and re-run without going through questions again:

python3 scripts/migrate.py --config .logseq-to-obsidian/config.json

Or via the Node wrapper:

logseq-to-obsidian --config .logseq-to-obsidian/config.json

Script Options

analyze_graph.py

python3 scripts/analyze_graph.py <logseq-path> [--sample-size N] [--json]

• --sample-size: Number of files to analyze (default: 50)
