Problem:
A Named Range in an Excel spreadsheet can theoretically have 1,048,576 rows and 16,384 columns. However the Microsoft ODBC driver will only process the first 256 columns.
Issue:
As one would expect, a Named Range of this size can have performance implications when uploading a spreadsheet to the iDashboards Cloud.
Resolution:
iDashboards has imposed the following Excel Named Range constraints:
A Named Range cannot have more than 255 columns. If it does, iDashboards will stop reading after 255 columns. Customers will get a warning about this when uploading a spreadsheet.
Customers can still use column ranges (where the whole column is selected to create the Named Range) but 200 consecutive blank rows in a named range will be interpreted by iDashboards as the end of the named range. That is, no data after 200 consecutive blank rows in a Named Range will be processed. This ‘truncation’ is silent, no warning will be issued to the user.
