I have a csv files with 600+ rows. There is no problem reading into Power BI Desktop but when read into Power BI dataflow, I encountered the following issues:
1. Columns with mostly 0 are read as all 0 -> tried sorting but end up other columns will end up becoming zero.
2. decimal numbers that are very small are read as 0 (e.g. 0.00000184 is read as 0) -> in order to avoid small decimals that are read as 0, i have converted it into text but small decimal ends up being read as scientific format 12E05 and not able to convert back into numbers.
