Which application can I download in order to read docs send in that format
For example, PDF files can be opened on the phone without a 3rd party app but if you want to view other docs like xls, ppt, txt then you'll have to download apps from play store example Microsoft office apps
Google docs, Microsoft Word -.doc
Google sheet, Microsoft excel-xls
Google slide, Microsoft PowerPoint-pptx
I use this, it's quite good 👍🏻
