Yes, you can. JetReader has built-in support for importing stats from Moon+ Reader, as well as a general CSV format.

Importing from Moon+ Reader

In order to import from Moon+ Reader, you need to create a backup from Moon, then import this backup in JetReader.

In Moon+ Reader, enter Options, and click 'Backup' at the bottom of the window.
Select whatever backup target you want (Local storage is easiest if JetReader is running on the same device).
Enter a filename, and keep note of where it is saved. You do not need to check any of the 'Include [something extra]' boxes.
In JetReader, go to Settings => Reading statistics, and click 'Import from Moon+ backup'.
Browse your file system, and find the backup file you just made from Moon+ Reader.
Depending on the filenames and metadata of the books you import, and whether they exist in you JetReader library, you may have to manually tell JetReader which books some of the imported stats belongs to.

Importing from CSV format

If you have your reading statistics in a format that is CSV-like, you can format it in a way that JetReader understands, and import it directly.

JetReader understands the following column headers:

date (date)
deviceid (text, a unique device id)
bookid (text, a unique book id)
filename (text, the file name of the book)
booktitle (text, the title of the book)
bookauthors (text, the author(s) of the book)
fromprogress (decimal number, at what percentage did you start reading this day)
toprogress (decimal number, at what percentage did you stop reading this day)
words (decimal number, the number of words read this day)
seconds (decimal number, the number of seconds read this day)
pageturns (integer, the number of pages read this day)
sessions (integer, the number of times you opened the book this day)
sessionid (text, a unique id that connects all rows belonging to the same reading session)
finisheddate (date, when you finished reading this book)
rating (integer, from 0 to 5)
comment (text)

Dates must be in a common format understood by C#'s DateTime class. For example yyyy-mm-dd is safe to use.
Decimal numbers must use a dot (.) as their decimal separator.

Importing from other apps

If you are using another reading app, let me know which one, and I can help you either convert it to CSV, or create an automated importer for other apps.
