      Hi,

      Thanks for your response.
      Sorry i forget to tell that i’m using groupdocs to convert office documents and pdf to HTML.
      1. Excel
      • Show Grid means, if i don’t have borders - html will not show cells borders.
      • Ok i see it showing multiple worksheets (earlier the other worksheets was empty, that’s why i didn’t saw).
    1. PowerPoint:
      • Ok got it
      • The question is it possible to have pagination on html page? Now all the converted documents have no pagination, it have just scrolling down concept. We want something similar to Office 365 (sharepoint) powerpoint online viewer.
      • I’m using HtmlSaveOptions - not possible to use what you suggest, i think
    2. Pdf:
      • Same thing as with powerpoint pagination.

      As I said, my manager wants similar to office 365 document viewer. And there another question about file preview? Can it be achieved by reduce font-size and show in popup or may be some another way?

      Hi,

      Thank you for the details.

      Converting office documents to HTML format allow these HTML Options in this release.

      HtmlSaveOptions htmlSaveOptions = new HtmlSaveOptions();

      htmlSaveOptions.ConvertFileType;

      htmlSaveOptions.CustomName;

      htmlSaveOptions.NumPagesToConvert;

      htmlSaveOptions.OutputType;

      htmlSaveOptions.PageNumber;

      htmlSaveOptions.UsePdf;

      1. Excel:

      a. Yes it renders same formatting as original file, if original file have borders then it only display borders for those cells.

      2. PowerPoint:

      a. It converts all slides in a same single file; however you can specify number of slides to convert. For example you can convert one slide and render as HTML and on your custom pagination event you can convert other slide and render as HTML and so on.

      3. Pdf:

      a. Same applies as PowerPoint pagination.

      We suggest you to please look for our great product GroupDocs.Viewer that will cover your requirements.

      Hi

      I’m back to use GroupDocs.Conversion and code my own js pagination.

      But we still have questions:
      1. Excel - is it possible to keep showing cells borders (not user borders, but excel cells borders itself)? May be possible add some custom style to add borders?
      2. Word document have page framing (it’s separating with borders) but others files do not have this? is it possible to turn on? I know I can add my own style, just asking if your library can do it without my effort.
      3. Looks like Conversion library have no Watermark support unlike Viewer, am i right?
      4. We found some presentation problem in powerpoint for table. Please refer to attachments.

      Hi

      Thanks you for your answers

      1. Ok, but is it possible for me to add some css to turn on borders for all cells?
      2. I’m asking about PDF document - there no page border?
      3. Ok
      4. See attachment (attached zip archive)
      11

      Hello ,


      Thank you for the providing details, Please see our answer
      for each points.


      1. Currently it is not possible to add CSS using
        GroupDocs.Conversion API but you can achieve that by converting document to
        HTML format and add inline style for table border and you can keep the html
        format or can convert html to any other document format.
      2. You can convert PDF document page by page to HTML and add
        border style for each page and use that HTML to convert in any other document format.
      3. Ok
      4. We have tested Conversion scenario
        with your provided presentation document and we found issues in conversion. We have
        logged this issue and notified our Product team for the solution .When we will have any news from our Product team about this issue, we will notify you.We apologize for the inconvenience.


      If you will need any help or you will have any other
      questions please feel free to ask.

      Hello,

      Thanks for your help, I’m appreciate it.

      You told me that it possible to add inline style for converted excel document. But there is no ‘table’, it convert with using ‘div’, and if i add border to these divs - it will not looks like excel cells. Am i doing something wrong?

      I also have some technical questions, if you can help:
      1. I have some pdf document, and when I call ConversionHandler.Convert(str, FileName, options) it hang and never respond. I know it does not depend on file itself, but depends on the stream (i have different different storage types, like azure, aws). So, do you know under what condition this method can hang? May be i can turn on some logging?

      2. I’m now displaying converted HTML in bootstrap modal. The problem I faced that for Excel and PDF documents - the images (background and others) moving out of their correct place. I found that it can be fixed for my case by set css ‘zoom: 0.875;’ to div with class ‘stl_03’. After i set - all looks fine. I have attached screen shot with problem. Do you have exp of such issue? May be you have any idea what can cause this?

      I know both problem are very specific problems, i’m just asking on possible reasons of my issues.

      Hello,


      Thank you for appreciating and sharing details.

      Yes it is true converted HTML render table as DIV tags and classes for each DIV, I am afraid you need to apply custom style for DIV.

      1. We have tested this (Stream to use with Azure, AWS) scenario using a some big size PDF file like 3 MB of file to convert in to HTML and result as in Stream and it works perfectly.
      • You can try to first convert file to HTML and read in stream and output path to local system/server and then use stream object OR read file from path and save to Azue,AWS.
      2. We have also tested this scenario and rendered HTML file display same formatting as original file But when we use converted HTML with custom CSS in page like Bootstrap effect the formatting by overwriting CSS classes.
      • You will required to handle your custom theme/Bootstrap classes to use converted HTML.

      If you will need any help or you will have any other questions please feel free to ask.

      Warm Regards

      Hi


      For excel and custom style for div it’s not true as it’s not possible. It will not looks like a cells


      Ok, your answers was not really helpful, but thanks anyway.

      Another qn about excel. Since it support multiple sheets - is there i can extract Sheet name and use as label in the beginning of the next sheet? is there an indication that there another sheet starts?
      15

      Hello,

      Sorry for the inconvenience, We are trying our best to make our next generation API’s to do jobs easily and high performance although all scenarios cannot be cover .

      To convert Excel file to HTML/Images you can convert page by page / Sheet by Sheet, please have a look at sample code using HtmlSaveOptions

      var saveOptions = new HtmlSaveOptions

      {

      PageNumber = 2,

      NumPagesToConvert = 1,

      OutputType = OutputType.String

      };

      var convertedDocumentPath = conversionHandler.Convert<string>(“E:/SampleExcel.xlsx”, saveOptions);

      Note: There is a limitation in evaluation version for all pages conversion (try to use first three sheets to test scenario).

      We have new release of GroupDocs.Conversion API for .NET scheduled soon with more options/features and fixes; please wait till that as that will cover more scenarios.

      If you will need any help or you will have any other questions please feel free to ask.

      Hi

      Sorry, but you are not answering on the question.
      I’ve asked is it possible to differentiate different sheets? from your codes you are converting page by page, but not sheet by sheet. As I see now, it’s not possible. and there no sheet name I can find.


      Do you have scheduled date for new release? Is there release notes for your upcoming release?


      While testing today, I can see that excel is weak side of GroupDocs.Conversion. Hope new release will fix the issues

      Document 1. somehow the last page (there 3 sheets by 1 page in each) have different css class. all have stl_02, but last one - stl_10. So when i tried to add page borders - last page have different size, but without borders it cannot be observed.

      Document 2. This is complex document. Multiple sheets (9), different tables. So it does not return me all the pages. Cannot provide you this doc, i will try create similar excel and replicate with it.

      Hi,


      Sorry for the inconvenience. we have tested the Page by Page scenario for HTML output as well Images output, however the for rendering images working as each sheet converts to an Image file but for HTML rendering by using Paging there are issues and it does not convert each sheet as a separate page.

      PageNumber property in actual is a SheetNumber it is working for Image rendering but not for HTML rendering.

      We have reported this issue to Product team once we have any update from them we will inform you here.

      New release 3.1.0 of GroupDocs.Conversion for .NET is now available with CallBack and FileType features with more improvements; however these new logs are not covered in this release and will be consider for fix and improvements.

      Thanks you for your patience.

      Hi

      Thanks for sharing link for new release, i’ve downloaded.

      I’ve attached document, that i talked about in my previous post. Can you help me verify whether you see the issue in conversion of this excel or not. And is this the same issue as in your last post or it’s new. Thanks

      I have fixed by myself issue with document 1, just force to use css class ‘stl_02’ for pages for excel converted html. But this one (document 2 issue) i cannot fix.

      I’ve also added style for page numbers for PDF and WORD documents. I think it’s useful and will be good that your library can do it as an option.
