CSV

Transposed

Features

  • Swap rows and columns
  • First row becomes the first column
  • Keeps the detected delimiter
  • Useful for “metrics as columns” vs “metrics as rows”

Common Use Cases

  • Flip a wide export into a tall table
  • Turn a year-as-column sheet into year-as-row
  • Prepare data for a charting tool that wants the other orientation
  • Make a matrix readable

Transpose is mechanical

Cell (r, c) moves to (c, r). Headers are just the first row of the grid. There is no type inference.

Examples

Valid - 2x2
a,b
1,2
