I'm trying to print out a dataframe from pandas into Excel. Here I am using to_excel() functions. However, I found that the 1st column in Excel is the "index",
0 6/6/2021 0:00 8/6/2021 0:00
1 4/10/2024 0:00 6/10/2024 0:00
2 4/14/2024 0:00 6/14/2024 0:00
Is there any ways to get rid of the first column?
You need to set index=False in to_excel in order for it to not write the index column out, this semantic is followed in other Pandas IO tools, see http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.to_excel.html and http://pandas.pydata.org/pandas-docs/stable/io.html
index=False does not work if you have MultiIndex columns (as of Pandas 1.3.4, Oct 2021). NotImplementedError: Writing to Excel with MultiIndex columns and no index ('index'=False) is not yet implemented.Example: index = False
import pandas as pd
writer = pd.ExcelWriter("dataframe.xlsx", engine='xlsxwriter')
dataframe.to_excel(writer,sheet_name = dataframe, index=False)
writer.save()
I did that and got the error message:
TypeError: 'DataFrame' objects are mutable, thus they cannot be hashed.
The code is as follows where 'test' is a dataframe with no column names
test = pd.DataFrame(biglist)
writer = pd.ExcelWriter("test.xlsx", engine='xlsxwriter')
test.to_excel(writer,sheet_name=test, index=False)
writer.save()
Ok Don't set the Sheet_name to the dataframe. I think you want the sheet name to be "test". It looks like the issue is in the sheet_name that you have set.
test = pd.DataFrame(biglist)
writer = pd.ExcelWriter('test.xlsx')
test.to_excel(writer, sheet_name="test", index=False)
writer.close()
