How to read Excel files from a stream (not a disk-backed file) in Python?

Question

XLRD is installed and tested:

>>> import xlrd
>>> workbook = xlrd.open_workbook(\'Sample.xls\')

When I read the file through

Answer 1

What I met is not totally the same with the question, but I think maybe it is similar and I can give some hints.

I am using django rest framework's request instead of pylons request.

If I write simple codes like following:

@api_view(['POST'])
@renderer_classes([JSONRenderer])
def upload_files(request):
    file_obj = request.FILES['file']
    from xlrd import open_workbook
    wb = open_workbook(file_contents=file_obj.read())
    result = {"code": "0", "message": "success", "data": {}}
    return Response(status=200, data=result)

Here We can read using open_workbook(file_contents=file_obj.read()) as mentioned in previous comments.

But if you write code in following way:

from rest_framework.views import APIView
from rest_framework.parsers import MultiPartParser
class FileUploadView(APIView):
    parser_classes = (MultiPartParser,)

    def put(self, request, filename, format=None):
        file_obj = request.FILES.get('file')
        from xlrd import open_workbook
        wb = open_workbook(file_contents=file_obj.read())
        # do some stuff with uploaded file
        return Response(status=204)

You must pay attention that using MultiPartParser instead of FileUploadParser, using FileUploadParser will raise some BOF error.

So I am wondering somehow it is also affected by how you write the API.
