I have a problem with rich text in Spire.Doc, I am trying to add rich text in a paragraph using AppendHTML, but I get the following exception: "The input string was not in the correct format". I don't know why this problem arises as I am passing a string to the AppendHTML.

Hello,

Thank you for your inquiry.
According to your description, could you please confirm whether your rich text is in HTML or RTF format? If it is in RTF format, you need to use AppendRTF(string rtfCode) method. If it is in HTML format, I suggest you try again with our latest Spire.Doc Pack(hot fix) Version:9.10.9. If the issue still exists after trying, please share us with your rich text as well as your complete test code for our reference. You could attach them here or send them to us via email (support@e-iceblue.com). Thanks in advance.

Sincerely,
Annika

Yes, the text is html and yes, the problem persists even with the latest version, I think the problem is with the width tag, if the width tag has decimals, the SPIRE fails.

I attach a raw example.

Hello,

Thanks for your sharing.
After investigation, I found that the issue you mentioned is caused by not standard HTML code. I directly changed the suffix of your file to .html, and opened it with Google Chrome and found that the standard HTML code was displayed. Copy the HTML code to a new file and open it again with Google Chrome to display the correct content. I tested the standard HTML code with Spire.Doc and the result is completely correct. I have attached my test project for your reference.

Sincerely,
Annika
