How to paste tabular data into an HTML table

I have an HTML tabl开发者_JAVA百科e on a webpage and can edit the contents manually. However, it would make my life much easier if I can copy the data from a file to the clipboard and just paste in onto the form. Can BHOs in IE do this? Any pointers will be helpful.

I have a superset of the data in a file and I don't want to type it all into the webpage.

If your file can be saved as a CSV (using Excel or some other program), then you can use a tool such as the one here (or write your own) to convert it to HTML.
