Import & export

Leaving Lar is meant to be as easy as arriving. Every import path also has an export counterpart where it makes sense, and nothing is locked into a proprietary format.

Export

• JSON — the full workspace plus body content, round-trip capable.
• Markdown — one file per Object, frontmatter for properties + relations, body as Markdown.
• HTML and print-ready PDF.

Import

Source	What happens
Roam Research (JSON)	[[backlinks]] and ((block-id)) references pass straight through into Lar’s wikilink and block-ref layer.
Obsidian vault (.md folder)	A second resolution pass links cross-vault [[Note]] references after every file is imported.
Evernote (.enex)	HTML bodies convert to Markdown; <tag> elements become real Tag Objects; timestamps are parsed.
OPML 2.0	One Object per outline node; hierarchy is preserved via the mentions relation.
ICS calendar	Each VEVENT becomes an Event Object, de-duplicated by UID on re-import.
Readwise (bring your own token)	Each book becomes a Weblink Object with its highlights as body blocks, grouped by source.

Imported and captured content always lands as on-device Objects first — none of it round-trips through a vendor server to get into Lar.

Migration guides

Bulk import is not a one-click migration — set up your Object Types and clean up the source content first, then run Settings → Import Content → Start importing.

Notion {#notion}

Export from Notion as Markdown & CSV (“Export all workspace content”), then feed the resulting .zip to the import flow. Pages keep their folder hierarchy; database .csv files become Objects; cross-page links resolve across the whole export.

Obsidian {#obsidian}

Point the import flow at your vault folder. Every .md file becomes an Object, and a second pass resolves cross-vault [[Note]] references once all files are in.

Evernote {#evernote}

Export notebooks as .enex. HTML bodies convert to Markdown, <tag> elements become Tag Objects, and timestamps are preserved.

Apple Notes {#apple-notes}

Apple Notes has no bulk export — use a converter (e.g. Exporter on the Mac App Store) to produce Markdown files first, then import those.

Tana {#tana}

Export your workspace from Tana as Markdown (or JSON converted to Markdown) and import the resulting files.

Other tools {#other}

Anything that can produce Markdown, CSV, OPML, ENEX, or ICS can come in through the same flow; unrecognized files are stored as file-backed Objects with their original bytes attached.
