Urgent excel2pdf conversion problem

We are post production and came across the following bug. We are due in production which makes this an urgent matter for us.

We created the Excel file using OpenXml and when trying to convert it to PDF we get the following exception:

Test method Leumi.PdfUtilities.Infrastructure.Test.FileConverterTest.ExcelToPdfConversionTester.TestExcelToPdfConversionWithNullParam threw exception:

System.FormatException: Input string was not in a correct format.

Result StackTrace:

at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal)

at System.Number.ParseInt64(String value, NumberStyles options, NumberFormatInfo numfmt)

If the file is manually opened with Excel and re-saved from Excel then the conversion succeeds, this is of course not a viable option outside of development.

Hi,


There is one more problem: while converting this excel to pdf, some rows of the chart legend are missing.
Please your check ASAP.

Thanks

Hi,

Thanks for your feedback and using Aspose.Cells.

We have tested your issue with the latest version Aspose.Cells for .NET 8.6.2 and the output pdf looks fine. All the chart legends are good. Please download the output pdf and highlight your issues by adding comments inside it. You can also provide us screenshots highlighting the issues with red circles. It will help us look into your issue more precisely and we will update you asap.

C#
string filePath = @“D:\Downloads\MessageExample±+Copy.xlsx”;

Workbook workbook = new Workbook(filePath);
workbook.CalculateFormula();

PdfSaveOptions opts = new PdfSaveOptions();
opts.OnePagePerSheet = true;

workbook.Save(filePath + “.out.pdf”, opts);

See the problem in the attached example (attached the source excel and result pdf)

Hi Dvir,


I am afraid, we are not able to pin point any problem in your generated PDF nor in the PDF we shared earlier in our previous response. That is the reason we asked you to share the PDF after highlighting the problematic areas along with code used for conversion so that we could focus on those areas to assist you further in this regard. If you like, you may also share snapshots of the highlighted problematic areas. Thank you for your understanding and cooperation.

Attached a snapshot of the problem. The chart contains 5 colors, but the legend contains only 3 rows.

The legend in the source excel is OK (see the file I attached before).

Hi,

Thanks for your posting and using Aspose.Cells.

We were able to replicate this issue with the latest version: Aspose.Cells for .NET 8.6.2 and found that some entries of the chart legend get missing while saving to pdf as per your screenshot.

We have logged this issue in our database for investigation. We will look into it and fix this issue. Once the issue is resolved or we have some other update for you, we will let you know asap.
