Hi. This might come handy for people working with heterogeneous data before passing it to gretl. I'm using them along the scripts discussed earlier on this list for making seasonal adjustment of several variables at once, but of course using this + your custom scripts could help you in analysing your excel data faster with gretl if that's how you get or preprocess your information before being ready to using it. You select a range in excel, press the hotkey assigned and gretl opens with the data you selected. If the series are in the form of rows instead of columns, use the second macro "rangos_a_gretl_y_transponer" which transposes the range before sending it to gretl. The macros are kind of robust, they work on excel 2010 32bit + windows 7 and excel 2007 + XP and vista + 2007.
