Hi SachinVelankar;
Specifically, there is a Word folder off the root of the archive structure. Within this
Word folder, there should be a document.xml file. This is usually where the trouble is and would be noted by the error message you received; e.g. Unspecified error Location: Part: /word/document.xml, Line: 2, Column: ×××. This is
where the problem is 99% of the time but check the error message to be sure. If it points to another internal XML file than the word/document.xml then that other XMl file would be the place to look.
This assumes that the problem is within the XML coding of the document. There is another common form of corruption that occurs when working directly to and from a removable device like a USB thumb drive. If this is the case, you need some professional grade
.ZIP repair software to repair the archive (aka .ZIP) structure before you can even access the internal files.
As mentioned, if you would like someone to attempt repair on your document, you will need to upload a copy of your damaged DOCX to a public file area like OneDrive, DropBox or Google
Drive and post the location to the publicly shared file back here.
