Convert

Convert (Misc)

Workflow-specific conversions. Each pair supports round-trip conversion.

Command	Description

List to Table (Two-Column)	Indented list → 2-column table (children joined with `<br/>`). Headers: `Key` / `Value`
Table to List (Multi-Column)	Multi-column table → indented list (`Header : Value` format)
List to Table (Multi-Column)	Indented list → multi-column table (columns derived from `Header : Value` entries)

Explorer Check

Right-click a file or folder in the Explorer → Markdown Doc Toolset. Results appear in the Problems panel, which opens automatically when issues are found.

Command	Description
Check : Missing Final Newline	Detect files that do not end with a newline
Check : Line Endings (non-LF)	Detect files containing CR+LF, CR-only, or mixed line endings

Check : NFC Normalization	Detect files containing non-NFC characters (e.g., NFD dakuten)

Folder mode: subdirectories are scanned recursively. NBSP / Non-ASCII report the first occurrence per file; all other checks report all occurrences.

Command	Description
Normalize Date Prefix	Rename `yyyymmdd`-prefixed files and folders to `yyyy-mm-dd-` format (Docusaurus standard)

File Path

Command	Description
Open in Associated App	Open the path at cursor with the OS-associated application
