Is there a limit on number of Journal lines or number of rows that can be uploaded via ADFdi or FBDI

1) is there a limit on number of lines a Journal can have

2) What is max

number of rows that can be uploaded via ADFdi(JournalEntry.xlsx) or FBDI (JournalImportTemplate.xlsm, cant upload due to extenstion).

I found an article ADFdi Vs File Based Import For Importing Journals (Doc ID 1622476.1), but it talks about the High volumes, and performance. But does not provide exact number of rows that can be loaded by these two method. And also does not tell how many rows can be added using UI. We are in middle of conversion in production, wanted understand these limits
