无法使用 pandas 将完整的 pivot 表写入现有 excel 工作簿中的新工作表

Question

I am able to write the pivot table generated a new sheet in an existing workbook, but when I open the excel file I dont see the indexes, I see only values. However I can see the complete pivot correctly in terminal.

I created this file:

writer = pd.ExcelWriter('Output.xlsx')

I have this in a sheet in the above file created:

lookup = pd.merge(ns,sfdc[['Account ID','Account Status']],on=['Account ID'],how='left')

lookup.to_excel(writer, sheet_name='latest_sg',index=False)

I did a pivot table:

pivot = lookup.pivot_table(index=['Account ID','accountname'],values=['gb'],aggfunc='sum',fill_value=0)

pivot.to_excel(writer, sheet_name='pivot', index=False)
writer.save()

in terminal I get the output for:

print(pivot)

                                              gb
Account ID   accountname                     
1-1          ABC Inc.                         0
1-2          DEF                              1
1-3          XYZ                            974
1-4          TRX                             00

But in the Output.xlsx I get a new sheet as 'pivot that gets created but the sheet has only GB column:

gb
0
1
974
00

The excel sheet does not show complete pivot table details. Please help

There is problem MultiIndex is removed in to_excel , because index=False parameter.

Correct solution is remove index=False , but then possible empty row after header:

pivot.to_excel(writer, sheet_name='pivot')

Or convert MultiIndex to columns by DataFrame.reset_index and then not write default Rangeindex with index=False :

pivot.reset_index().to_excel(writer, sheet_name='pivot', index=False)
