I imported an xl spreadsheet data into sql server database. I notice that
some columns data is NULL even though the data exists in spreadsheet.
However, the entire columns isn't null, some columns it converts correctly
whereas for others it puts <NULL>. I tried converting the column into both
text and numeric fields, but I got same results. This is happening for a few
columns, some columns have been converted correctly.

Any ideas as to why it may be happening? How can I fix this?

I need to fix this asap as I have project deadline to meet.

If this is not the right group for this question, please let me know.

Thank you very much,
