sheet = wb.sheet_by_index(0)
  
for i in range(sheet.nrows): 
    print(gs.translate(sheet.cell_value(i, 0), 'de'))
    print(sheet.cell_value(i, 1)

I am receiving the below error

The error is caused because you don't have a B is empty and package does not read the column from sheet.

To write the translated result to the sheet, you can do something like this:

I don't think xlrd can write to sheet. You will need to use xlwt package. You will need to install it pip install xlwt

import xlrd
import xlwt # this package is going to write to sheet
import goslate
loc = "dummy.xlsx"
translated = "dummy2.xlsx" # location to where store the modified sheet

gs = goslate.Goslate()

# crate a workbook using xlwt package in order to write to it.
wbt = xlwt.Workbook() # there is a typo here. this should be wbt
ws = wbt.add_sheet('A Test Sheet') # change this to your sheet name

rwb = xlrd.open_workbook(loc) 
sheet = wb.sheet_by_index(0)
  
for i in range(sheet.nrows): 
    ws.write(i, 0, sheet.cell_value(i, 0)) # this will write the A column value
    ws.write(i, 1, gs.translate(sheet.cell_value(i, 0), 'de')) # this will write the B column value

wbt.save(translated) # this will save the sheet.

As for making changes in the same file, I my opinion you should not do that. The file is already opend by another process in read mode. Changing it can result in unexpected behavior. But if you intent to do that, backup your file, and set the loc for both when reading and when saving file.

You're getting the error because xlrd addresses columns are zero based and per documentation the xlrd ignores cells with no data.

so you could access column A by doing

sheet.cell_value(i, 0)

and write to column B by doing

sheet._cell_types[i][1] = xlrd.XL_CELL_TEXT
sheet._cell_values[i][1] = source

however xlrd is only for reading, so you'd have to use xlwt to save any changes.

Saving changes brings up another issue, you're source file is ".xlsx" extension, while xlrd does read this format, xlwt only writes to the older ".xls" format.

To read and write to ".xlsx" format with one library you can use openpyxl, using this library your code would look like this:

import openpyxl
import goslate

loc = r"C:\path\fruits.xlsx"
gs = goslate.Goslate()

wb = openpyxl.load_workbook(loc)
sheet = wb.active

for i in range(2, sheet.max_row + 1):
    original = sheet.cell(row=i, column=1).value
    translated = gs.translate(original, 'de')
    sheet.cell(row=i, column=2).value = translated
    
wb.save(loc)

This code is not working gives me below error `Traceback (most recent call last): File "c:\Users\userid\translation.py", line 14, in translated = gs.translate(source, 'de') NameError: name 'source' is not defined` — Shan, Oct 05 '20 at 13:57
on that line `source` should have been `original`, I fixed the code in answer. — Jpsh, Oct 05 '20 at 20:42
