Labview/Excel question

Hi,
How would I go by appending data to an existing excel file? so that it
doesn't overwrite the data that is already written, it just continues from
where it left off?


Thanks,
Rob

Search NI website example VI's. There is one VI that lets you write to the
specific cell range, so you could modify it to open an existing file.

Make one spreadsheet cell into a pointer to the last entry. For the next
write use that pointer to determine where to start. Most likely it would be
faster than parsing the spreadsheet.
