Im using a two dimension array having the limitation of 17000 colloumn and 4096 rows and which i save as a spread sheet file. while using this much size my application is very slow.
Is there are any options to handle through spread sheet in labVIEW?
How to allocate dynamic memory for this two dimension array?

First, you are responding to a thread which is 8 years old. You probably would have been better off starting a new one.
Spreadsheet files are text files so the numeric values need to be converted to text. With almost 17 million elements that is a lot of conversion. The files will be around 0.5 GB, depending on the format or how many characters per element will be saved. A binary format might be better.
Search for a white paper on Handling Large Datasets. That has lots of good information about memory allocation for large arrays.
