Throwing "Unknown Function with id [257]" exception when saving file (2410)

Hi,

I am writing to you about a problem we encountered in working with MSO Excel documents using the Aspose Cells for Java 20.3.0 library. In particular, when we load an Excel document whose format is “.xls” and immediately (without any changes) try to save it, the exception “com.aspose.cells.CellsException: Unknown function with id [257] (” Based on Chart “at Sheet1! D 3)” is thrown.

I am enclosing the zip file with source code, as well as the source and target Excel files.

In the hope that together we will quickly overcome the problem!
Best regards!

Nenad

@zpredojevic,
I have tried to reproduce this issue using the latest version but could not reproduce it. Could you please try the following sample code using the latest version and share your feedback?

String sourceFileDirFile = "source\\";
File sourceFile = new File(sourceFileDirFile, "unknownFunction.xls");
Workbook excel = new Workbook(new FileInputStream(sourceFile));
String excelTargetFilePath = "target\\unknownFunction-done.xls";
excel.save(excelTargetFilePath, SaveFormat.EXCEL_97_TO_2003);
