unable to read and write Excel spreadsheet data in GAMS

Hi dear all,

I am trying to read an excel sheet in GAMS and create a GDX file from it. But I recieve these error messages :
**** GDX ERROR AT LINE 87

  • Open read failed C:\Users\hohn\Documents\gamsdir\projdir\Randomdata.gdx

**** GDX ERROR AT LINE 87 - Msg: No such file or directory
Here is the lines 86 and 87

[/execute 'gdxxrw.exe i="stochasticopy.xlsx" o=Randomdata.gdx par=Rdata rng=
      "Sheet2"!A1 MaxDupeErrors = <10>  ';]
[code][/ execute_load 'Randomdata.gdx', Rdata;]

Please help me to solve this: Thanks

Hi

Add “Trace = 3” at the end, and you will see if your import of data works well. If there are errors for all imported variables, your gdx file will not be created.

Ok thanks!

Thanks Gams, I did that and no errors appeared.
