Importing data from Excel files¶
Add the AIMMSXLLibrary Library.
Go to File > Library manager.
Click Add System library… and select AIMMSXLLibrary. Click OK.
Create a procedure.
Create a procedure to import data from the Excel document. For example,
Open the Excel file:
axll::OpenWorkBookto open your workbook.
Tip: If you send a command to open a workbook which is already open, AIMMS raises an error. You can use an
IFblock to check whether a workbook is open or not, and open if it is closed or otherwise select the open workbook.
WorkBookName := "zipcode-database.xlsx"; if axll::WorkBookIsOpen(WorkBookName) then axll::SelectWorkBook(WorkBookName); else axll::OpenWorkBook(WorkBookName); endif;
Specify a sheet of the workbook.
axll::SelectSheetto specify which sheet of the workbook to pull data from.
sp_Sheet := "Example"; axll::SelectSheet(SheetName : sp_Sheet );
Import data from the Excel file to your AIMMS project.
Use the appropriate
axll::function to read data from the Excel sheet.
The ReadTable statement will be:
axll::ReadTable( IdentifierReference : MyValue, RowHeaderRange : "A8:D18", ColumnHeaderRange : "E4:K7", DataRange : "E8:K18");
axll::ReadSetto read in data for the set
axll::ReadSet( SetReference : sStates, SetRange : "D2:D42523", ExtendSuperSets : 1);
axll::ReadListto read in data
ZipCodeState(z), which holds the state name that each zip code belongs to.
axll::ReadList( IdentifierReference : ZipCodeState(z), RowHeaderRange : "A2:A42523", DataRange : "D2:D42523");
Close the Excel file.
axll::CloseWorkBookto close the workbook.
