Hello,
If you are developing with SAPUI5 and you want to generate Excel spreadsheets you have different options.
If you want more info about ABAP2XLSX just check the following links ABAP2XLSX Wiki or ABAP2XLSX Github. Thanks to ivan.femia and contributors.
To show how this can be done just continue reading.
We can build a sapui5 application with a simple button that executes a function import, the function import implemented in the backend will build the excel and return as binary, back again in the navigator you can offer the file to download. Here a simplified workflow:
First let's do the odata part using the SEGW Gateway Builder and create a Complex Type 'excel' with reference to structure VALSTRUCTX.
Include the VAL property as binary type, in backend the type is rawstring
Then create a function import getExcel, the return type has to be the complex type we created before:
Now let's do the implementation for the function import getExcel, just enter to the method /IWBEP/IF_MGW_APPL_SRV_RUNTIME~EXECUTE_ACTION and build an excel using ABAP2XLSX ( here we are using the demo12 example 😞
Second we create a SAPUI5 application with just one view, in that view a button that will call a method in the controller called "getExcel"
In the controller we add the following methods:
The final result will be a button in the view, when you press it will automatically offer the excel:
You can generate graphics:
And also play with styles, just for fun:
So if you want to offer you users great excels from sapui5 I think with abap2xlsx you can offer a good solution.
Thanks for reading
If you are developing with SAPUI5 and you want to generate Excel spreadsheets you have different options.
- Use the class sap.ui.core.util.ExportTypeCSV and export as CSV, so this is not a fancy excel spreadsheet.
- If you are on SAPUI5 version 1.50 or higher you have the class sap.ui.export.Spreadsheet, it's ok if you only want a table and filters, right now is not supporting lot of features excel offers.
- You can also use external libraries like sheetjs but to have all features available you need a license.
- One great option is to use ABAP2XLSX to generate the excel in the backend and show it in the frontend.

ENDMETHOD.Second we create a SAPUI5 application with just one view, in that view a button that will call a method in the controller called "getExcel"
<mvc:View xmlns="sap.m" xmlns:mvc="sap.ui.core.mvc" xmlns:semantic="sap.f.semantic" controllerName="ztest_excel.ztest_excel.controller.Worklist">
<Panel id="__panel0">
<content>
<Button xmlns="sap.m" text="Export Excel" press="getExcel"/>
</content>
</Panel>
</mvc:View>In the controller we add the following methods:
s2ab: function(s) {
var buf = new ArrayBuffer(s.length);
var view = new Uint8Array(buf);
for (var i = 0; i != s.length; ++i) view[i] = s.charCodeAt(i) & 0xFF;
return buf;
},
getExcel: function(oEvent) {
var successGetExcel = function(oData, oResponse) {
if (oData.getExcel) {
var a = window.document.createElement('a');
var blob = new Blob([this.s2ab(atob(oData.getExcel.Val))], {
type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'
});
a.href = window.URL.createObjectURL(blob);
a.download = 'Excel.xlsx';
// Append anchor to body.
document.body.appendChild(a);
a.click();
// Remove anchor from body
document.body.removeChild(a);
}
};
this.getModel().callFunction("/getExcel", {
method: "GET",
success: jQuery.proxy(successGetExcel, this)
});
},The final result will be a button in the view, when you press it will automatically offer the excel:
You can generate graphics:
And also play with styles, just for fun:
So if you want to offer you users great excels from sapui5 I think with abap2xlsx you can offer a good solution.
