Alexandria
Tana is built around nodes, supertags, and fields. In Alexandria, the closest mapping is:
Alexandria tag properties support boolean, select, multi-select, date, number, money, and string. Tana fields that behave like status, dates, numbers, checkboxes, or text usually map cleanly. Reference-heavy or relation-like fields do not have a direct Alexandria property type today; preserve those as note text or Markdown links during conversion.
Not yet supported. There is no automated Tana importer yet - this is a manual process today.
Alexandria's automated import path is currently focused on Notion; see Imports. Tana can export data as JSON or Markdown, but Alexandria does not yet read those exports directly.
A realistic workflow today:
For a small Tana workspace, manual cleanup may be faster than scripting. For a large workspace, test a conversion on a small export first and keep unsupported Tana structures visible in the note body rather than silently dropping them.
Tana's graph-like structure is richer than Alexandria's current importer support. The cleanest migration usually keeps important writing as Markdown notes, keeps supertags as tags, and preserves complex references as readable text until Alexandria has a dedicated Tana importer.
