Apply borders to all cells in a range with openpyxl

Question

I have a script that takes a pandas dataframe and chops it up into several hundred chunks and saves each chunk as a separate excel file. Each chunk will have the same number

Answer 1

seems there is no built-in for this task, and we have to make some steps ourselves, like:

#need make conversion from alphabet to number due to range function
def A2N(s,e):
    return range(ord(s), ord(e)+1)
#B1 is the border you defined
#Assume you trying border A1-Q1 ... A3-Q3
X = A2N('A','Q')
#print X    
your_desired_sheet_range_rows = range(1,4)
#need two loop to go through cells
for row in your_desired_sheet_rows:
    for col in X:
        ca = chr(col)
        sheet[ca+str(row)].border=B1
