Hi Far,

1. I am not aware of anything to do with the use of Arabic or Persian that would affect the macro. In any event, when I run the macro with the workbook you supplied, ك is replaced by ک.

2. If you have many terms and a large document, processing may seem slow, but there is nothing that can be done to make the code run faster, except for getting a faster computer. The code is already about as efficient as it is possible to make it.

3. Except for the file extension, the code should not need any modification to work with html files. If you want to be able to process files that don't have a .doc, .docx or .docm extension, change '.doc' in 'strFile = Dir(strFolder & "\*.doc", vbNormal)' to match whatever file type you want to process. For example, 'strFile = Dir(strFolder & "\*.html", vbNormal)'.
