[somesh g]

Hi..there

I have written code for reading the large excel files

but my requirement is to read a particular cell in a excel file when i kept "True"

in "wb = load_workbook('Path', True)"

any body please help me...

CODE:
====
from openpyxl import load_workbook

wb = load_workbook('Path', True)
sheet_ranges = wb.get_sheet_by_name(name = 'Global')
for row in sheet_ranges.iter_rows():

for cell in row:
print cell.internal_value
