Import from Nimbus Note

[egolector]

Good morning. I would like to know if it is possible to import some 20,000 notes from Nimbus Note (which exports in html format) into Notesnook without losing formatting, highlights, tags and especially attachments, because almost half of my notes have attachments.
Many people are abandoning Nimbus Note after the switch to Fusebase which has disappointed everyone who used the programme to collect and manage notes and annotations. Thank you!
