Sorting thru a cell collection in openpyxl

Question

I am reading in an xlsx file, like so,

import openpyxl
book = openpyxl.load_workbook('test.xlsx')
sheet = book.get_sheet_by_name(sheets['DATA'])
allCells = sheet.get_cell_collection()
print allCells

allCells is an unordered list of openpyxl.cell.Cell objects. allCells looks like,

[<Cell Data.B4>, <Cell Data.A6>, <Cell Data.B6>, <Cell Data.A1>, <Cell Data.B5>, <Cell Data.A3>, <Cell Data.A2>, <Cell Data.A5>, <Cell Data.B1>, <Cell Data.B2>]

I want to sort this list by column and then by row indices. Any ideas on how to do this?

Answer 1

You can get row and column information for every cell in the list like so:

import openpyxl
wb = openpyxl.workbook.Workbook()
ws = wb.worksheets[0]
a=ws.cell('D6')
a.row
6
a.column
'D'

Now it's just a matter to sort the lot according to any criteria that you desire. Here's a list of different algorithms to be used for sorting. And this post describes how to sort a list according to objects' attributes. What is the problem? I'll edit the answer accordingly.
