Preview Documents without prior conversion

Hello Community,
Is there any mechanism that would NOT require the documents to be converted to Image or HTML in order to be rendered ?
We are looking for a solution that would not require any conversion. I went through the various C# examples available but I could not find any way to preview documents without them being converted first.
Am I missing something obvious here ?
Thank you.

@JeromeMARGET,

Thanks for posting to our forum.

I am afraid that you can not render/view the documents without conversion to HTML or images using GroupDocs.Viewer. In case you would have any other question or query, please feel free to let us know.

Hi Aziz,
Thanks a lot for your response.
Do you, by any chance, have any other solution that do not require any conversion prior to render any file format. Any other tool apart from GroupDoc Viewer ?
Thank you.

@JeromeMARGET,

Thanks for coming back to us.

I am afraid that there is no other solution or the tool that allows rendering/viewing of the document without conversion to HTML pages or images. Please feel free to let us know in case of any other queries.
