【Urgent】Excel data analyzer format is not available

In my understanding, to use Excel data analyzer, Excel data analyzer format is inevitable, but which is not available for exporting data in Kobo. How can I download it? With XLS format, the analyzer does not work well, even though using some tricks such as converting text to number, changing to list name from list_name. Questions appears well, but the chart, graph, tables do not appear. Please teach me if i needd some more steps. [ FYI, i already watched 8A,B,C Data Analisys video and try everything here]
Thank you for reading and your help in advance.

Welcome to the community, @yuta! Maybe going through the documents user manual should be helpful.

Thank you for reply. But I already read it through. It seems like no tips to solve this.
