CSV to Markdown Table (and back)

Convert CSV/TSV into a Markdown table — and convert a Markdown table back into CSV or TSV.

Works on the current selection, or the whole file when nothing is selected.

Commands

Command	What it does
Convert CSV/TSV to Markdown Table	Delimited text → aligned Markdown table
Convert Markdown Table to CSV	Markdown table → CSV
Convert Markdown Table to TSV	Markdown table → TSV (paste straight into a spreadsheet)
Align Markdown Table Columns	Re-pad an existing table so the source lines up

Available from the Command Palette and from the editor right-click menu.

Most converters split on commas. That quietly corrupts real data:

name,note
apple,"red, ripe"
pear,"say ""hi"""

This extension parses per RFC 4180, so quoted delimiters, escaped quotes ("") and newlines inside quoted fields all survive. It also:

detects the delimiter (comma, tab, semicolon, pipe) instead of assuming commas
escapes | and newlines in cells so the generated table is always valid Markdown
squares off ragged rows rather than emitting a broken table
converts back, which most alternatives do not

Setting	Default	Meaning
`csvMarkdownTable.alignColumns`	`true`	Pad cells so columns line up in the source
`csvMarkdownTable.firstRowIsHeader`	`true`	Use row 1 as the header; when off, headers are generated

No telemetry. No network requests. No account. No data collection of any kind. Everything runs locally on the text in your editor.
