Hi Experts,

I have worked in one SAP UI5 Project , and i was having one requirement that User's will upload the huge Excel file , and that has to be read in browser side (Client side) and file line item has to pass into Odata / PI interface, i have tried many other ways but browser was responding slow due to huge data to read and convert into required Format .

Finally i have found the this JS class and logic which is best way to fullfill the requirement without any weighted to browser.if you want to read uploaded Excel / CSV data from the Portal Application , this is the best way to read DATA from the file and move it into JSON format

So Kindly Find the below steps and code  and required class,

1 step : below files need to add in your project and need to call as shown below

jQuery.sap.require("*******.util.xlsx");
jQuery.sap.require("*******.util.xlsxfullmin");

 

Step 2:  Main Function to read the data with the help of xlsx class

function ProcessExcel(reader) {

var workbook = XLSX.read(reader, {
type: 'binary'
});

 

NOTE:  For more logic kindly find the controller file below , w is also contain read data from excel and converting to Json Format and slo table binding 

  1. Below screen with Excel data

Conclusion  :   Without any time Consuming we can read a huge data from the File in client side Browser. Reading files and converting into required format into a browser side is normally  it will take much time to get the data if file contains more line items ,  But By using "xlsx.js" "xlsxfullmin.js" files now it's very easy and in fraction of seconds possible to get the data into our required format even file having huge data line item.

Hi Jun Wu,

Kindly Find the below more details on sort and filtration. with screenshots and code as below

Total 17 records as shown below screen

Sort and Date Range for filtering data as below screen.

Date created filed filtration based on recent created record in TOP (descending order )

CODE:  for sorting and descending order for the “dateCreated” field

reId.sort(function(a,b) {return (a.dateCreated < b.dateCreated) ? 1 : ((b.dateCreated < a.dateCreated) ? -1 : 0);} );

find the full filtration code below .

if you sort the batch number column, will your pagination show correct data?

Yes ,  please change change the field name in sort and check,

you can also use as below code to sort

.sort(function(a, b){return a - b});

Hi Vaibhav,

 

Thank you for the post.

I used your code to upload around 20k records from excel but the browser got stuck for 5 minutes.

Is there any other way to reduce the response time?

 

Thanks

Can you please share you code and the excel  file data

so i can check and let you know if anything is missing or can add something which may works faster,
