Help with gams, gdx and xlsx

Post by dgormaz » 5 months ago

hello, I'm trying to pass several cells of different sheets of an excel to gams using gdx, and I get strange errors, this I have until now:
Parameter DH1 (K0, J01)
$ call GDXXRW Alt_Tables.xlsx par = DH1 rng = H1(K0,J01)! A1: B7 output = DH1.gdx
$ GDXIN DH1.gdx
$ LOAD DH1
$ GDXIN

Parameter DH2 (K0, J02)
$ call GDXXRW Alt_Tables.xlsx par = DH2 rng = H2(K0,J02)! A1: AB7 output = DH2.gdx
$ GDXIN DH2.gdx
$ LOAD DH2
$ GDXIN

Parameter DH3 (K0, ND01)
$ call GDXXRW Alt_Tables.xlsx par = DH2 rng = H3(K0,ND01)! A1: I8 output = DH3.gdx
$ GDXIN DH3.gdx
$ LOAD DH3
$ GDXIN

At the beginning it appears that the sheet does not exist, then I write again the name of the sheets in excel and the program recognizes them, this is very rare. The other strange thing is that he does not run me because he tells me that the DH3 has 'symbol not in gdx' since I can open DH3.gdx Does anyone know what the problem is?
Thank you!

  • Having characters outside [a-z][A-Z][0-9] in sheet names might confuse the command line of gdxxrw
  • Always check the return code when you do a $call with $if errorlevel 1 $abort "problems with the $call command"
  • You might want to post you spreadsheet so one of us can try to reproduce

I have no problems whatsoever reading the data with gdxxrw with the following code:

Code: Select all

$onecho > gdxxrw.in
i=Tablas_Alturas.xlsx
o=data.gdx
par=DH1 rng=H1(K0,J01)!A1:B7
par=DH2 rng=H2(K0,J02)!A1:AB7
par=DH3 rng=H3(K0,ND01)!A1:I8
$offecho
$call gdxxrw @gdxxrw.in
$if errorlevel 1 $abort "problems with gdxxrw"

set K0,J01,J02,ND01;
Parameter DH1(K0,J01), DH2(K0,J02), DH3(K0,ND01)

$gdxin data
$loadm K0<DH1.dim1 K0<DH2.dim1  K0<DH3.dim1
$load J01<DH1.dim2 J02<DH2.dim2 ND01<DH3.dim2
$loadDC DH1 DH2 DH3
display DH1, DH2, DH3;
There were plenty of spaces in the code in your original posting. They will confuse gdxxrw. Moreover, your third call to gdxxrw was saving the results again in DH2 but you try to extract DH3. So I am not sure what you really tried.

I need to transport some parameters from *.gdx file into excel.
I would like to do it precisely column by column, no transportation of columns into rows.

My code is the following:

Code: Select all

execute_unload 'VarToBrugegruppe.gdx', qabg quabg qsabg;
execute 'gdxxrw VarToBrugegruppe.gdx o=TabelA15.xlsx filter=1 trace=1 par=qabg rng=qabg!A2'
The excel output is attached. I was trying to play with trace and filter options to have the year span as column as well - like in .gdx file. So what I need is to have all (six) dimensions as columns with extra (seventh) column containing values of my parameter.
And get the names for the columns as well.

Can you help me to fix this problem?

Best
Irena

Hi Jarenka

Why don't you add rdim=5 cdim=1 to your call to read this data?
Otherwise, reformulate your question and attach code and the excel sheet.
Cheers
