Hi Amjad_Sahi,

I have attached the excel file also find the below code snippet:

Workbook book = new Workbook(“Path of the excel file”);
Worksheet sheet=book.getWorksheets().get(0);
Cells cells = sheet.getCells();
Object[][] exportArray = cells.exportArray(0, 0, cells.getMaxDataRow()+1, cells.getMaxDataColumn()+1);

@rahul0711,
I have tried this scenario using latest version Aspose.Cells for Java 20.3.x but could not observe this issue. The values are fetched similar to the values shown by MS Excel. Please try this sample code with the latest version and share the feedback.

Hi ahsaniqbalsidiqui,

I have even tried with latest version of aspose cell java 20.3 and still the values are not matching please refer currently attached file also refer the below code snippet and output:

Workbook book=new Workbook(“filepath”);
Worksheet sheet= book.getWorksheets().get(0);
Cells cells=sheet.getCells();
Object[][] exportArray=cells.exportArray(0, 0, cells.getMaxDataRow()+1, cells.getMaxDataColumn()+1);
for(int i=0;i<exportArray.length;i++){
for(int j=0;j<exportArray[i].length;j++){
System.out.print(exportArray[i][j]+" ");
}
System.out.println();
}

	} catch (Exception e) {
		// TODO: handle exception
	}

@rahul0711,
We were able to observe the issue in Windows environment but we need to look into it more. We have logged the issue in our database for investigation and for a fix. Once, we will have some news for you, we will update you in this topic.

This issue has been logged as

CELLSJAVA-43163 – Aspose.Cells giving different fraction value as compared to MS Excel

P.S. We tested the same issue in macOS, but no difference is observed when compared with values in MS Excel.

@rahul0711,
We have analyzed your issue and observed that the exported values are the original ones saved in the template file. MS Excel uses 15-digits for numeric values for display and most of other features, but for Java on Windows platform by default the digits is 17 for double to string. To get the same with what is shown in MS Excel, you need to truncate those values to 15-digits by yourself.

Hi ahsaniqbalsidiqui,

My Concern is why 17485.1180423 number which is less than 15 digits getting as 17485.118042299997
if i truncate this value to 15 digits it will give 17485.1180422999 which again doesn’t match with excel

@rahul0711,

“Truncate” just means decreasing the digits of the numeric values. In another words, you should round/set the value to 15 digits.

Hi Amjad_Sahi,

Actually there is not regularity in the numbers what i am getting in export
for eg :

  1. 17485.118042299997 if round it and get 15 digits ill get 17485.1180423 which is same as excel.

  2. 62.96209420153875 if i round it and get 15 digits i get 62.9620942015388 which doesn’t match with excel

@rahul0711,

Thanks for your feedback and details.

We will evaluate and get back to you soon.
