from openpyxl import Workbook, load_workbook

wb=load_workbook("/home/ilissa/Documents/AnacondaFiles/AZ_Palmetto_MUSC_searchterms.xlsx", use_iterators=True)
sheet_ranges=wb['PrivAlert Terms']

for row in sheet_ranges.iter_rows(row_offset=1): 
    for cell in row:
        print(cell.value)

this is an alternative to previous answers in case you whish read one or more columns using openpyxl

import openpyxl

wb = openpyxl.load_workbook('origin.xlsx')
first_sheet = wb.get_sheet_names()[0]
worksheet = wb.get_sheet_by_name(first_sheet)

#here you iterate over the rows in the specific column
for row in range(2,worksheet.max_row+1):  
    for column in "ADEF":  #Here you can add or reduce the columns
        cell_name = "{}{}".format(column, row)
        worksheet[cell_name].value # the value of the specific cell
        ... your tasks... 

I hope that this be useful.

Python Language, How do I read an Excel file in python XLRD? If you don’t feel comfortable in pandas, or for whatever reason need to work with openpyxl, the error in your code is that you aren’t selecting only the first column. You explicitly call for each cell in each row. If you only want the first column, then only get the first column in each row. for row in sheet_ranges.iter_rows(row_offset=1):

Using openpyxl

from openpyxl import load_workbook
# The source xlsx file is named as source.xlsx
wb=load_workbook("source.xlsx")

ws = wb.active

# Print the contents
for x in xrange(len(first_column)): 
    print(first_column[x].value)

Comments
  • did you mean: for row in range(2,worksheet.max_row+1): instead of for row in range(2,worksheet.max_row):?
  • Hi, no. Because worksheet.max_row return the highest index with elements on it, if you add +1, the last row it will be an empty line. It´s possible to check for more examples here:openpyxl
  • yeah, but for the function range, the second param is exclusive. This way we would miss the data from the last row
  • Aha, you are right, in my case the last row had a different value for the column, for that reason I didn`t notice the mistake, I will make the correction now, thanks!
  • This will still return one row at a time.
  • ws.rows is generator and I am getting "object of type 'generator' has no len()" maybe max_row?
  • What happens when your sheet actually enough columns that there is actually a column 'AB' ?
