How to tamper a MS word document being downloaded from a website

[jjs]

I am testing a website.  I had success in altering the HTTP request and headers etc - as a man in the middle.  Now I want to be able to alter the contents of an MS Word (.doc or .docx) or .txt file being downloaded by the browser.  I am unable to do it. Can any body tell me how this can be done.  Please help.

Hi, jjs--

It would be helpful if you explain exactly what you've tried to do thus far, and what exactly happened when you did it. Modification of text files is no different than modification of HTML files; modification of .doc/.docx files is only slightly different insofar as you need to use the Inspectors that work with binary content (e.g. the HexView) and avoid those that only work with textual content (e.g. the TextView).

Hi Eric, thank you for your reply.  It helped me take another look at the HTTP response being intercepted and I realised that the content of the file being downloaded too was available in the intercepted response body.  I was able to make modifications to the text portions of the .doc or .xls file that was being downloaded.  I was able to get my work done.  

Thank you.

JJS Anand.
