Import ZKN3 archives into Obsidian

Background

Deleted slots matter because later notes keep their original positions. The importer uses those positions for file names and repeat-import matching, rather than renumbering the live notes.

2 ways to do it

Recreate selected notes as Markdown
Keep the source application open and copy chosen note text into Markdown files. Name each file with its source position, then add supported headings, keywords and internal links by hand.
Obsidian’s syntax guide documents headings and wikilinks. Check each target against the source before adding a link or ordered note sequence.
limits
You transfer keywords and relationships yourself. This method provides no archive preview or automatic repeat-import matching.

Zettelkasten Archive Import from this site
Save the version 3.8 archive and open it with Import a Zettelkasten 3 archive. Check live notes, deleted slots, missing targets and unsupported markup before selecting Create notes.
Keep the same import folder for later imports, and retain zkn3_position on imported notes. Pro can compare two archives, but imports skip existing notes rather than updating changed ones.
limits
Attachments and several other archive components are not copied. Review the report and keep your original archive for reference.

Common questions

Why does the output skip a source number?

An empty source slot represents a deleted note. Later live notes keep their positions so their links do not shift.

How should I review a later archive?

Use Pro comparison to inspect added, changed and removed positions before importing. Review changed notes separately because the import only creates new notes.
