Using QGIS select Raster/Conversion/Translate (Convert format) ... from the menu. Select the ASCII Gridded XYZ file type and set the output file. It will execute a gdal_translate command as you can see it in the dialog. gdal_translate -of XYZ input.tif output.xyz

Note: it will use the raster value of the first band as Z value if you have a multiband image (e.g. RGB).

  • Enable GDALTools plugin in the Plugins/Manage and Install plugins dialog.

  • The final step, then, is to import the .xyz file into Excel. Excel treats the xyz file as a text file and uses the import wizard to allow you to set the delimiters. It seems obvious now, but it took me a little time to work that out.
