How to delete rows that satisfy some criteria in an excel spreadsheet?
I would like to create a "reduced" version of an Excel (xlsx) spreadsheet (i.e. by removing some rows according to some criterion), and I'd like to know if this can be done with openpyxl.
In (pythonish) pseudo-code, what I want to do would look something like:
wb = openpyxl.reader.excel.load_workbook('/path/to/workbook.xlsx')
sh = wb.get_sheet_by_name('someworksheet')
# weed out the rows of sh according to somecriterion
sh.rows[:] = [r for r in sh.rows if somecriterion(r)]
# save the workbook, with the weeded-out sheet
wb.save('/path/to/workbook_reduced.xlsx')
Can something like this be done with openpyxl, and if so, how?

2018 update: I was searching how to delete a row today and found that the functionality is added in openpyxl 2.5.0-b2. Just tried and it worked perfectly. Here's the link where I found the answer: https://bitbucket.org/openpyxl/openpyxl/issues/964/delete_rows-does-not-work-on-deleting
And here's the syntax to delete one row:
ws.delete_rows(index, 1)
where: 'ws' is the worksheet, 'index' is the row number, and '1' is the number of rows to delete.
There's also the ability to delete columns, but I haven't tried that.
