Restrict access to Excel file

Paid on delivery
I have an Excel file. When I provide it to someone, I want that particular file to open up on their computer (or whichever computer they open it on) only and no subsequent computers. So I am essentially looking for a way to have an Excel file tied to one particular machine. I don't have the necessary knowledge to say what software or solution I want for my needs, nor do I know what budget I would need, so I would like freelancers to provide a proposal with a suggested solution to this problem. I have thought about getting a small piece of software which the Excel document would be linked to and only opened through that particular piece of software. And this particular software could only ever be installed on one machine. I look forward to your suggestions.

What i would suggest is to have an executable that can open the excel file in it. There will be a license file generated by you for each computer where you want to install. It will take the MAC address,processorid,hardisk id etc for that computer and will only work where the license permits. Please message me so that we could discuss in detail.

Hello, I am very much interested to do this interesting work. I have strong knowledge in excel macro and i want to do this work by it. I have a question, how do you want to specify a machine to tie the excel to it? Will you specify the computer name or mac address or what is your plan to recognize a machine/computer? Looking forward to have a positive response from you. Thanks

Hi there - My name is Paris. I've read your brief and can see that you'd like to have a macro-enabled Excel spreadsheet. I have 7 years’ experience designing and developing Excel spreadsheets. I would approach your project by creating a draft spreadsheet and send it to you for review. I am highly qualified for this project and would love to speak with you further about taking this project on. If you'd like to view my previous work, as well as feedback, take a look at my Freelancer Portfolio (https://www.freelancer.com/u/paris2785.html).

Hi, This scenario as described here can be achieved by a two tier encryption approach. The idea is that two separate applications will be developed (both of them will be C# Windows desktop applications), one of them will remain with you (as the sender of the excel file) and the other is what you will provide to your client. Your client will then run the app you sent to them to get a code. This code is produced based on his/her machine configuration and hence will not be the same for any other machine. He/she will then send that code back to you. You will then enter that code into the second piece of application which resides on your machine to encrypt the excel file using the user-specific code. The application will provide you with an encrypted version of the excel file that you can send back to your customer. The client application can decrypt the file and open it in excel for local use and then remove it when excel is closed. This is the whole idea. But I am not pretty sure how much time this will take to complete because of the nature of this kind of projects that involve an unpredictable amount of testing on different machines. So I’m bidding $100 and 3 days for now but please be informed that depending on how much it will take me to implement the project I might charge you for up to $200 more and I might be needing up to 6 more days.

Hello! I can propose next way: I will write a program that allow to set some stamp on the excel file - after that nobody can open the file, if you'd like to open it you should run the program again - it remove the stamp and open it by MS Excel, after finishing working with the excel file you should set stamp again. It prevent from opening excel file.

Hi, I can do this task for you. I would write it so that the data is encrypted and stored in a macro. If the computer is the one it was first opened on it would decrypt the data and populate the spreadsheet. Of course this wouldn't stop someone from just copying the data to a new spreadsheet, so I would suggest that the macro would prevent the copying of data as well (or disabling the clipboard while the program is open) I can start immediately and have this for you tomorrow (ie within 24 hours). Feel free to contact me to discuss the details of this project.

Hi, From proposal I understand that you want to protect your excel files with password. In this case, In MS excel itself we have an option to password protect any excel files. Also using this inbuilt feature even that password protected files is encrypted, so it becomes more safe. So whenever you want to open that excel file, you need to provide that already set password. Without that password, no one can ever open that file. If this is the kind of solution you are looking for, kindly revert back so that I can provide you with detailed instruction on how to set password.

With your requirement. I am thinking of using excel programming to restrict access to excel documents. I have done something like this before, but the restriction was on the network related not by machine. It was made to only allow users to open the file within the company networks. so for your project. 1. I can create an excel that will have a setup/configuration sheet or tab, where you can set the Machine name who can only access the file; or 2. I can create a separate excel document where you can set Machine names, and the file you want to restrict access. So you will have a master excel for the setup/config of access and the actual file as separate document.
