A malformed document is a document that has structural or formatting errors or is corrupted or incorrectly encoded. In some cases, malformed documents may be recovered within the application used to create the document by using its built-in repair capabilities.
The Document Is Malformed
If the Document Is Completely Malformed:
- Launch Excel and click Open in the left-side menu.
- Click Browse and locate the malformed file on your computer.
- Select the file, then expand the Open drop-down menu and select Open and repair.
- In the pop-up window, click Repair. If Excel is unable to repair the workbook, you can try Extract Data.
If the Document Is Only Partially Malformed:
- Create a new document with the same name.
- Copy over the contents of this document to the new document.
- Save the new document.
If the Document Is Unusable:
In this case, the only method for retrieving the document is through data recovery. If you have not created a backup of the file, you must recreate the document from scratch and reupload it to Panorama.
