React JS - edit RTF file

Job ID: 33707095

Budget: $15 – $25 USD

Need to React script to open RTF file. (www.url.com/rtffilesample.rtf) and edit the RTF syntax/content by adding a string; then triggering browser download of the new/updated rtf file.

I have added a sample rtf file and before and after images of what the updated file should look like.
