macro to access and read data from HDF files

Hi,

Does anyone know if Excel can be used to read data from HDF files? Specifically, what I would like to do is this: I have an Excel worksheet with some latitude data on Column A and longitude data on Column B. I would like to open a HDF file, which contains many sets of data, out of which 2 are the latitude/longitude data, and a third set contains the data that I want to extract. I will use the latitude data in Column A to search through the first set in the HDF, which will return me the row number. I will then use the longitude data in Column B to search through the second set to return the column number. With these row and column numbers, I will then extract the corresponding data in the third set, and write it to Column C in the worksheet.

If it is possible to do this, can someone kindly show me how to write a simple VBA code for it? Or point me to some relevant information?

Thanks for any inputs.

anyone at all?
