Excel has certain limitations such as:
- Column Limit: 255
- Row Limit: 64k
- cell contents (text): 1,024 Characters
In addition to this there are also other limitations because of which excel may be unable to load the file. The solution for this problem is to download a CSV-Raw Data file or the SPSS (.sav) file use that file.
QuestionBuilder cannot do anything about these limitations. These are limitations imposed by Microsoft/Excel not QuestionBuilder.
