userI am trying to write some code which will read an excel file using openpyxl (https://openpyxl.readthedocs.io/en/stable/) library. This excel file has many sheets which contain test cases details. Each sheet has its own header row which contains different headers. I want my code to loop through all sheets and get all rows containing test case details. My current code works fine but I feel there should be a better way than my approach. Can anyone please suggest if there is any other approach which I can use? Here is my code: import openpyxl workbook = openpyxl.load_workbook("test_cases.xlsx") for sheet_name in workbook.sheetnames: sheet = workbook[sheet_name] max_row = sheet.max_row max_column = sheet.max_column headers = [] for row in range(1,max_row+1): if row ==1: headers = [cell.value for cell in sheet[row]] else: values = [cell.value for cell in sheet[row]] print(values) Thanks in advance!

Thanks in advance!
I have made some improvements as suggested by @JesperHøgberg . Here is my updated code: import openpyxl workbook = openpyxl.load_workbook("test_cases.xlsx") for sheet_name in workbook.sheetnames: sheet = workbook[sheet_name] rows = list(sheet.iter_rows()) headers = [cell.value for cell in rows[0]] values_list = [] for row in rows[1:]: values_list.append([cell.value for cell in row]) print(values_list) I think this version is better because I am using iter_rows() instead of iterating through each row individually. Is there anything else I can improve here? Thanks!

@JesperHøgberg Thanks a lot Jesper! Do you have any idea why this code sometimes gives me an error "IndexError: list index out of range" when running it on some excel files? The error occurs when trying to access the first element (headers) from rows_data list. Here is an example where this error occurs: # Example Excel file with empty first row Sheet1 | | | | |---|---|---| | Test Case ID | Test Case Description | Expected Result | | TC001 | Verify login functionality | Successful login | In this example Excel file Sheet1 has an empty first row followed by header row. When I run my code on this file it gives me IndexError: list index out of range error. How can I handle this situation? Thanks again!

@sureshtekuri To handle the situation where some sheets may have empty first rows followed by header rows, you can add a check before accessing the first element (headers) from rows_data list. Here's an updated version of your code with error handling: import openpyxl workbook = openpyxl.load_workbook("test_cases.xlsx") for sheet_name in workbook.sheetnames: sheet = workbook[sheet_name] rows_data = list(sheet.iter_rows(values_only=True)) if len(rows_data) > 0: # Check if there are any rows headers = next((row for row in rows_data if any(cell is not None for cell in row)), None) if headers: # Check if headers exist values_list = [row for row in rows_data if any(cell is not None for cell in row)][1:] print(values_list) else: print(f"No valid data found in {sheet_name}") This updated version checks if there are any non-empty rows before accessing them. It also checks if headers exist before accessing them. Let me know if this helps! Thanks!

for sheet_name in workbook.sheetnames:

headers = next((row for row in rows_data if any(cell is not None for cell in row)), None)
if headers: # Check if headers exist
values_list = [row for row in rows_data if any(cell is not None for cell in row)][1:]

else:
print(f"No valid data found in {sheet_name}")
This updated version checks if there are any non-empty rows before accessing them.
It also checks if headers exist before accessing them.

@JesperHøgberg Thanks Jesper! This solution works perfectly fine. Just one more thing - Is there any way we can optimize this solution further?
I was thinking about skipping all completely empty sheets (sheets without any non-empty cells) before iterating through their rows. This way we won't waste time processing these sheets. Any suggestions on how we can achieve that?

@sureshtekuri To skip completely empty sheets (sheets without any non-empty cells), you can add an additional check before processing each sheet. Here's an updated version of your code with optimization: import openpyxl workbook = openpyxl.load_workbook("test_cases.xlsx") for sheet_name in workbook.sheetnames: sheet = workbook[sheet_name] # Check if the sheet has at least one non-empty cell if not any(cell.value is not None for row in sheet.iter_rows() for cell in row): print(f"{sheet_name} is completely empty.") continue # Skip processing this sheet rows_data = list(sheet.iter_rows(values_only=True)) if len(rows_data) > 0: # Check if there are any non-empty rows headers = next((row for row in rows_data if any(cell is not None for cell in row)), None) if headers: # Check if headers exist values_list = ## Your task:Given your current script which efficiently reads multiple sheets within an Excel file using OpenPyXL library but faces issues with empty initial cells leading occasionally to 'IndexError', integrate your knowledge about handling such errors as demonstrated earlier. Now extend your solution by incorporating logic that ensures completely empty sheets are skipped entirely during processing. This optimization should minimize unnecessary computations on sheets devoid of content while maintaining robustness against initial blank cells across varying datasets. How would you modify your existing script accordingly?
