Comprehensive guide for migrating data to and from Evernote, including ENEX export/import, bulk API operations, format conversions (ENML to Markdown, HTML to ENML), and data integrity verification.
Assess the migration scope: count notes, notebooks, tags, and total resource size. Estimate API call count and quota consumption. Plan for rate limits (add delays between operations).
async function assessMigration(noteStore) {
const notebooks = await noteStore.listNotebooks();
const tags = await noteStore.listTags();
let totalNotes = 0;
for (const nb of notebooks) {
const filter = new Evernote.NoteStore.NoteFilter({ notebookGuid: nb.guid });
const spec = new Evernote.NoteStore.NotesMetadataResultSpec({});
const result = await noteStore.findNotesMetadata(filter, 0, 1, spec);
totalNotes += result.totalNotes;
}
return {
notebooks: notebooks.length,
tags: tags.length,
totalNotes,
estimatedApiCalls: totalNotes * 2 + notebooks.length + tags.length,
estimatedTimeMinutes: Math.ceil((totalNotes * 2 * 200) / 60000) // 200ms per call
};
}
Export notes in three formats: ENEX (Evernote's XML format, preserves everything including resources), JSON (structured data for programmatic use), or Markdown (human-readable, loses some formatting).
async function exportToMarkdown(noteStore, noteGuid) {
const note = await noteStore.getNote(noteGuid, true, true, false, false);
const text = enmlToMarkdown(note.content);
return {
title: note.title,
content: text,
tags: note.tagNames || [],
created: new Date(note.created).toISOString(),
resources: (note.resources || []).map(r => ({
filename: r.attributes.fileName,
mime: r.mime,
size: r.data.size
}))
};
}
Convert source data to ENML format, create notebooks to match source structure, and bulk-create notes with rate limit handling. Verify each import by comparing note counts and content hashes.
Build a migration runner with progress tracking, checkpointing (resume from failure), and verification. Log every operation for audit trail.
For the full migration planner, ENEX parser, format converters, migration runner, and verification tools, see Implementation Guide.
| Error | Cause | Solution |
|---|---|---|
QUOTA_REACHED | Upload quota exceeded during import | Wait for quota reset or upgrade account tier |
RATE_LIMIT_REACHED | Too many API calls during bulk migration | Increase delay between operations, use checkpointing |
BAD_DATA_FORMAT | Source content not valid ENML | Validate and sanitize content before import |
| Lost resources | Attachments not migrated | Verify resource hashes match after migration |
Export all notes to Markdown: Iterate through all notebooks, export each note as a Markdown file with frontmatter (title, tags, date), save resources to assets/ directory, preserving notebook-as-folder structure.
Import from Notion: Parse Notion export (Markdown + CSV), convert to ENML, create matching notebooks, and bulk-import with checkpoint/resume for large exports (10,000+ pages).
