How to convert JSON to XLS in Python

Question

Does anyone know how can I convert JSON to XLS in Python?

I know that it is possible to create xls files using the package xlwt

Answer 1

In case someone wants to do output to Excel as a stream using Flask-REST

Pandas versions:

json_payload = request.get_json()

with NamedTemporaryFile(suffix='.xlsx') as tmp:

    pandas.DataFrame(json_payload).to_excel(tmp.name)

    buf = BytesIO(tmp.read())

    response = app.make_response(buf.getvalue())
    response.headers['content-type'] = 'application/octet-stream'

    return response

and OpenPyXL version:

keys = []
wb = Workbook()
ws = wb.active

json_data = request.get_json()

with NamedTemporaryFile() as tmp:

    for i in range(len(json_data)):
        sub_obj = json_data[i]
        if i == 0:
            keys = list(sub_obj.keys())
            for k in range(len(keys)):
                ws.cell(row=(i + 1), column=(k + 1), value=keys[k]);
        for j in range(len(keys)):
            ws.cell(row=(i + 2), column=(j + 1), value=sub_obj[keys[j]]);
    wb.save(tmp.name)

    buf = BytesIO(tmp.read())

    response = app.make_response(buf.getvalue())
    response.headers['content-type'] = 'application/octet-stream'

    return response
