unable to read and write Excel spreadsheet data in GAMS

Post by ZNSen » 2 years ago

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

Code: Select all

[/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.

Cheers
