If you want to create a codebook for the appendix of a report, do not use the Export Codebook option that you find under the Import / Export tab. The purpose of this option is to transfer codebooks between projects or computers. The recommended option to create a code book is to use the Excel export option from the Code Manager:
Open the Code Manager and select Excel Export in the ribbon.
Select all options that you want to include. Essential options for a code book are codes and comments. You may also want to include groundedness, density and code groups.
Folders and independent codes are listed in the first column, categories in the second column, and subcodes in the third column.
