I developed some high performance Rust code to convert a vault from Wikilink to MDlink.
sumukshashidhar/performant-wikilink-to-markdown: High Performant Conversion of Referenced Wikilinks to Markdown. Use with LogSeq, Obsidian, etc. (github.com)
Please do let me know if this is helpful / something y’all would use! Also, do suggest the addition of features!
