Set empty cells to NaN or 0


= MLMissingDataAsNaN(flag)
MLMissingDataAsNaN flag
out = MLMissingDataAsNaN(flag)


= MLMissingDataAsNaN(flag) sets empty cells to NaN or 0. When the Spreadsheet Link™ software is installed, the default is "no", so empty cells are handled as 0s. If you change the value of MLMissingDataAsNaN to "yes", the change remains in effect the next time a Microsoft® Excel® session starts. Use this syntax when working directly in a worksheet.

MLMissingDataAsNaN flag sets empty cells to NaN or 0. Use this syntax in a VBA macro.

out = MLMissingDataAsNaN(flag) lets you catch errors when executing MLMissingDataAsNaN in a VBA macro. If MLMissingDataAsNaN fails, then out is a string containing error code. Otherwise, out is 0.

Input Arguments


Either "yes" or "no".

Specify "yes" to set empty cells to use NaNs. Specify "no" to set empty cells to use 0s.

Default: "no"

Output Arguments


0 if the command succeeded. Otherwise, a string containing error code.

Cancel the use of the value NaN for empty cells:



  • A string in an Excel range always forces cell array output and empty cells as NaNs.

  • To work with VBA code in Excel with Spreadsheet Link, you must enable Spreadsheet Link as a reference in the Microsoft Visual Basic® Editor. For details, see Installation.
