Help with uploading blank dates in my spreadsheet

[Kylevd23]

Hi guys, this is my first time here and I have a dilemma, so my system at
Work allows me to do mass uploads with excel spreadsheets
Instead entering in data line by line, however
There is a date column in which gets uploaded as well. The
Problem is if I upload a blank date field(which is what I want)
It will not upload the blank, for example in my current data I have
1/12/2012, but want to replace with a blank date. However
When I upload it says the blank data in the spreadsheet is not
In mm/dd/yyyy format and is invalid. I've tried using "" which
Comes back with the same error as well, any advice?

what is the field type of the uploading system for the date?

How are you uploading the data?

[Kylevd23]

Just short date format SQL datetime, not sure if you're referring to that

So the software which is Internet HTML format allows excel uploads into the database takes xls spreadsheets to upload large data
