I’m coding a Python 3.7.2 script to check for unused worksheets in an Excel file, and I need a way to determine if the current worksheet contains no values. Previously when I coded in VBA, I would find the last-used-row and last-used-column to check if the sheet was ’empty’, but the max_column and max_row functions in openpyxl take into account non-value data like formatting which I want to ignore. Is there any way to check if none of the cells of a given worksheet contain any values?

Ideally I’d be able to find a way to get the last_used_column and last_used_row like I used to in VBA, but I’d appreciate it if anyone could tell me of any tools I could use to build a simple function where you pass it a worksheet and it spits out True or False depending on whether it has no values or not.
In contrast to my suggestion in a comment, ws.get_cell_collection() is deprecated, but you could iterate over the openpyxl.worksheet.worksheet module’s
values property, since (from the docs):
values
Produces all cell values in the worksheet, by rowType: generator
With a workbook workbook.xlsx containing two worksheets, Sheet1 does contain some cell with values, but Sheet2 is visibly empty with all empty cells:
wb = load_workbook('workbook.xlsx')
for name in wb.get_sheet_names():
isempty = False
for row in wb.get_sheet_by_name(name).values:
if all(value == None for value in row):
isempty = True
else:
isempty = False
if isempty:
print(name)
outputs the empty sheet(s):
Sheet2
Although this works it is a bit more complicated than using only:
empty_sheets = [name for name in wb.get_sheet_names() if not (wb.get_sheet_by_name(name).get_cell_collection())]
which still works albeit deprecated.
