[英]Getting the excel file after df.to_excel(…) with Panda
I am using Pyrebase to upload my files to Firebase. 我正在使用Pyrebase将我的文件上传到Firebase。
I have a DataFrame df
and convert it to an Excel File as follows: 我有一个DataFrame df
并将其转换为Excel文件,如下所示:
writer = ExcelWriter('results.xlsx')
excelFile = df.to_excel(writer,'Sheet1')
print(excelFile)
# Save to firebase
childRef = "path/to/results.xlsx"
storage = firebase.storage()
storage.child(childRef).put(excelFile)
However, this stores the Excel file as an Office Spreadsheet with zero bytes. 但是,这会将Excel文件存储为零字节的Office电子表格。 If I run writer.save()
then I do get the appropriate filetype ( xlsx
), but it is stored on my Server (which I want to avoid). 如果我运行writer.save()
然后我得到相应的文件类型( xlsx
),但它存储在我的服务器上(我想避免)。 How can I generate the right filetype as one would do with writer.save()
? 如何生成正确的文件类型,就像使用writer.save()
?
Note: print(excelFile)
returns None
注意: print(excelFile)
返回None
It can be solved by using local memory: 它可以通过使用本地内存来解决:
# init writer
bio = BytesIO()
writer = pd.ExcelWriter(bio, engine='xlsxwriter')
filename = "output.xlsx"
# sheets
dfValue.to_excel(writer, "sheetname")
# save the workbook
writer.save()
bio.seek(0)
# get the excel file (answers my question)
workbook = bio.read()
excelFile = workbook
# save the excelfile to firebase
# see also issue: https://github.com/thisbejim/Pyrebase/issues/142
timestamp = str(int(time.time()*1000));
childRef = "/path/to/" + filename
storage = firebase.storage()
storage.child(childRef).put(excelFile)
fileUrl = storage.child(childRef).get_url(None)
