How to Password Protect a CSV File in Excel

CSV files are a format for storing text and comma separated values. There is no built in security or encryption, although there are third party programs that can be used. One way to password protect your data is to create a zip archive of the file. This is a good way to keep your data secure without having to send it over the pond in a secure container. However, it is best to store your encrypted CSV file somewhere that you can easily access from SSH (secure shell) so that you can retrieve your files when you need them.

It is possible to password protect a CSV file in Microsoft Excel. However, the process is a little technical and if you’re not familiar with the program, you might not know that you can even password protect your file in the first place. The good news is that it’s not as difficult as it sounds. First, you’ll need to find a password that’s both secure and unobtrusive. Once you’ve found a secure password manager, you can start adding your data to the spreadsheet. If you’re worried about losing the data, you can always restore it after you’ve password protected it.

You can also use a third party app to compress your CSV files. These apps can save you from having to deal with a big mess in your inbox. While you’re at it, you may want to consider encrypting the content of the zip file too. That way, you can add a password to it and enjoy the benefits of the encryption technology without having to worry about your confidential data.

You can even password protect an entire text file using a free plug-in. This is one of the most important steps you should take when using a file sharing program like SSH. Having a secure master password is a must, however.

You could also encrypt a PDF file with an app called PDFMate. The same software tool works for images and videos, so you’re not limited to the text file format. Another nifty trick is to create a “key” and encrypt the key with your chosen password.

Finally, there’s no reason you can’t password protect a CSV file in a nifty little app called Spotmau PowerSuite. The app’s UI is a tad confusing, so it’s a good idea to get some guidance from an expert. After all, you don’t want to end up with a bunch of useless CSV files. Upon entering a passphrase, you’ll get a small window that asks you to name your new file. From there, you can choose a nifty little CSV file to send to a colleague or store for later retrieval. As a bonus, the program also allows you to save the file as an xlsx format workbook, ensuring that you’ll never forget your key.

Of course, there are many programs that can password protect your data, but it’s a good idea to do a little homework and find a solution that works for you. For example, if you’re running a business, a local drive can be a great way to protect your valuables, while still keeping all of your files in a single location.
