Is Anytype can do similar with https://www.kgbase.com/ that can convert Table (Excel) to knowledge graph view ? Thanks.
It wouldn’t take too long to set up basically the same thing in Anytype but to answer your question, no you aren’t able to convert (or import) sheets/tables in Anytype.
You could make a feature request and maybe someone will make a plugin for this one day.
The good news is, after we improve our Markdown support, you should be able to import Tables from .md files.
