If you have data and need to annotate it one by one, you can use MS Access as a data annotation tool. Well, how?
1- Create new blank database
2- Import your excel as “internal data” to your app it will be table
3- Simply create a “form” from your table
4-Use your form for annotation (navigate with footer navigation buttons -they are very tiny)
5-Export the table after annotation
Here is one sample form from my works. As you see MS access can show dropdowns or checkbox that is very useful tools for annotation.
