Append data to the End of an Excel file

[lallilu87]

How can I add new data (of a new aquisition) to an existing excel file without erasing old data? I'd like to add the new data aquisition under the last data aquisition. I have not the excel toolkit.

I add here two file, the block diagram (i'm new in labview world  ) and what i see in excel when i run my VI. With the program I wrote, i can just save every aquisition in different excel file. 

I hope i have been clear, thank you for your time.

On the Write To Spreadsheet File function, there is a boolean input to append to file.  Set that to TRUE.
