Dear all,
Thank you for your compliments.
First of all, let me clarify one thing: I am not a professional Advanced Excel programmer. I am an amateur creator of Advanced Excel. Basically, I am a B.E. (Electrical Engineering) graduate working with R.P.G. Groups. I created all the Excel sheets in my leisure time to streamline our routine job work.
All my programs are user-friendly. You can put your company name/logo on any sheet, and there is no indication of its creator on any sheet (except the Main sheet), and all sheets are free. Upon closer inspection, you will find that I have not provided any password for formulas. You can view all logic in the taskbar. Additionally, all data entry cells have no password.
I have protected the sheets with a password for two reasons:
1. To optimize the performance of Excel, there are logic formulas that should remain hidden; otherwise, unauthorized entries in columns will disrupt the logic of the programs and may lead to incorrect results.
2. There are links from cells to other cells or sheets. To safeguard these links, we should not add or delete rows or columns in any sheet. If someone adds a new row or column, there is a risk of damaging the logic formulas (as the user might not know where I have placed logical formulas), which is why I have protected the sheets to prevent unauthorized additions or deletions.
3. For instance, if I have declared the file name "XYZ" for cells A1:A200, and someone adds a new row or copies and pastes the previous row, the logic may not function as expected because I have only declared cells 1 to 200 in my logic. Therefore, the program may not work correctly or may give incorrect values.
4. You cannot copy, paste, add, or delete new rows/columns due to the presence of formulas.
If a sheet is not password-protected and someone accidentally enters data in a logic cell or deletes a formula, it can be challenging to identify the error. Hence, I have implemented password protection to prevent unwanted entries in formula cells.
Unlike most professional creators who use passwords and offer demo versions to users, my programs are all full versions. The sole reason for the password protection is to avoid the issues mentioned above, not to charge or monopolize.
I have received some emails regarding the need for round figures in the programs. Some users require data in rounded figures, so I have made the necessary corrections and re-uploaded them on my website. If anyone needs such adjustments, please download them from the site.
I hope this provides a clearer explanation regarding the password. Additionally, for those looking to enhance their Excel skills, I have uploaded 200 books/materials for Excel programming, macros, and VBA on the aforementioned site, all available for free.
Thank you.
