What the conversion keeps and drops

Columns: Tabs copied from a spreadsheet, | tables, existing commas or semicolons, “Label: value” lines, and columns separated by two or more spaces are detected, in that order. Without columns, each line becomes one row.
Dropped: Blank lines, ASCII table borders, bullets in single-column lists, and padding around cells. Short rows get empty cells so every row has the same number of columns.
Protected: Cells that a spreadsheet would run as a formula, like =SUM(A1:A9), get a leading apostrophe. Values like -5, +1 555, and @name stay as they are.
CSV to TXT: Comma, semicolon, tab, or pipe delimiters are detected. Columns are aligned with spaces, line breaks inside cells become spaces, and very wide tables fall back to tabs.
