Dynamically Loading Multiple Excel Files

Dynamically Loading Multiple Excel Files

Hi Qlikers,

Firstly, kudos to avinashelite‌ for giving us the below method to load the all excel files with the multiple sheets.

Loading Multiple Excel Sheets Dynamically along with file name and sheet name

Using above method we can load the multiple excel files with multiple sheets even though all the sheets have different names.

Above method  works only in below scenarios

1)  When all the files having the same number of sheets.

2)  When all the sheets of excel files having the same number of Columns with same name.

But below method works even though you don't have same number of columns and sheets in excel and having blank sheet in excel.

// Define the Path

LET vExcelFilePath = 'D:\Test';
LET vQVDFilePath='D:\Test';


SUB CreateQVDFromAllExcelFiles(vPath)

FOR EACH vFileExtension IN 'xlsx'

FOR EACH vFile IN FILELIST(vPath & '\*.' & vFileExtension);

ODBC CONNECT TO [Excel Files;DBQ=$(vFile)];

Temp:
LOAD *;
SQLtables;
DISCONNECT;

Data:
LOAD * INLINE [
junk ]
;

FOR i = 0 TO NOOFROWS('Temp')-1

LET vSheetName = PURGECHAR(PURGECHAR(PEEK('TABLE_NAME', i, 'Temp'), CHR(39)), CHR(36));

CONCATENATE(Data)
LOAD  *,
FILEBASENAME() AS FileName,
'$(vSheetName)'
AS Sheet_name
FROM $(vFile)(ooxml, embedded labels, table is [$(vSheetName)]);

NEXT i


DROP TABLE Temp;
DROP FIELD junk;

NEXT vFile
NEXT vFileExtension

Set ErrorMode=0;
Drop Field A;     // When there is blank sheet in excel file, field A is created
Set ErrorMode=1;

STORE Data into $(vQVDFilePath)\FullData.qvd;
DROP Table Data;

END SUB

CALL CreateQVDFromAllExcelFiles('$(vExcelFilePath)');

LET i = Null();

Feel free to provide your suggestions

Thanks & Regards,

Kushal Chawda

Works like a charm!! Great work with it...

Hi Kush, Great work, but when i executing this script I am getting the "script Line erro" after this error script get executed sucessfully but why this script line error. Can you please help me out?

How you are executing the script? On which excel files you are executing this script?

Not applicable

I am using the same attached data and changed the path of the excels and QVD's in the script apart from this I have nothing changed in the script.

Can you post the application with path changes you have done. If you are using the same attached data and application it should work.

Hi

This is really a nice solution what would help me a lot. But

I have excel files with some hidden sheets inside (that happens while the source system generate and save the datas).

How can I use this code but ignore hidden sheets? Any ideas?

thx!

Have you tried loading the excel with hidden sheets? I have not considered this while developed the code. I will check and will get back to you on this
