Class Method Details

.load_meta_fields(file) ⇒ Object

A few rules about Excel files:

  1. .xls only, this can’t accept .xlsx

  2. There should be no empty cells in the header row of a sheet (first row)

  3. For good form, there shouldn’t be any subsequent rows that are longer than the header row

  4. There should not be any duplicate cell names in the header row
