Upload File to SharePoint through REST API

Question

Hello,

I am uploading ".xlsx " file into SharePoint online using REST API /_api/Web/GetFolderByServerRelativeUrl('-------')/files/add,

My upload is successful, but noticed after uploading file, it contains some additional comments as per below in the top of file, due to that, I am unable to process file .

Please advise.

Content-Type: application/octet-stream;
name=<....,XLSD>
Content-Transfer-Encoding: binary
Content-Disposition: form-data; name="filename"; filename="filename"

Answer 1

Yes, This has been resolved. Thank you.

Answer 2

Hi @Ramakrishnan Venkatesan ,
Per my test,I uploaded a file successful and correctly with following api:

_api/Web/GetFolderByServerRelativeUrl('/sites/abc/FolderTest/Test')/Files/add(url='rename.xlsx',overwrite=true)')  

We can set the file name after '/Files/add'. Since the error might caused setting filename by headers.
