Did you test against the latest CI build?

• Yes

If you answered No, please test with the latest development build first.

Version of ClosedXML

0.95.3

What is the current behavior? We are creating an excel file using the ClosedXML. Then we are using that excel file to convert in the Base64. There is some issue in file Excel creation by ClosedXML. So that file is not properly converted into the Base64.

What is the expected behavior or new feature?

• We need to encode & decode Excel file into the Base64 which is generated by the ClosedXML.

Is this a regression from the previous version?

Regressions get higher priority. Test against the latest build of the previous minor version. For example, if you experience a problem on v0.95.3, check whether it the problem occurred in v0.94.2 too.

Reproducibility

This is an important section. Read it carefully. Failure to do so will cause a ‘RTFM’ comment.

Without a code sample, it is unlikely that your issue will get attention. Don’t be lazy. Do the effort and assist the developers to reproduce your problem. Code samples should be minimal complete and verifiable. Sample spreadsheets should be attached whenever applicable. Remove sensitive information.

Code to reproduce problem:

using (XLWorkbook wb = new XLWorkbook())
                                {
                                    wb.Worksheets.Add(dt,"CategoryData");
                           
                                    //SAVE & UPLOAD FILE ON S3
                                    using (MemoryStream stream = new MemoryStream())
                                    {
                                        wb.SaveAs(stream,true);
                                        var IsSuccess = CommonFunction.tmpUploadBlogFileToS3(stream.ToArray(),Settings.TranslationExcelPath,FileName);                
                                    } 
                                }

Generate a good excel file that does work. Generate the bad one too. Save to disk instead.

Change file extension to .zip. Extract the files and do a diff on each file. Show the diffs.

Another thing you can do is open in excel and see if any warnings show. Save without doing anything in excel. Compare against the original bad file.

I am also facing the same issue. Can anyone help regarding this?

Is this library issue? I have tried using other libraries like EPPlus and its working well.

That file is truncated, not the full binary. As I said, this is not a ClosedXML issue. Closing this issue. Please use StackOverflow for further support.
