Mikey Bronowski shows us a few techniques for protecting data in Excel files using Powershell:

Last month we have been hiding things in Excel, so this week we are going to make sure they are protected as well. Excel offers multiple levels of password protection and its options:

– locking file with a password, i.e. without key phrase opening file is not possible
– protecting workbook’s structure
– lastly, protecting individual worksheets from a handful of operations

Read on to see each of those in action.

Aaron Nelson has one method for creating a polling loop in Powershell:

Originally I had used the Start-Sleep command to wait 3 seconds ( Start-Sleep 3
). That worked fine on my machine, but when I deployed it to the server, I found I needed to bump it up to 6 seconds. At first that worked, but then a week later I needed to bump it up to 9 seconds. The problem here is obvious, if we force it to wait 9 seconds every time, even if the task was updated after 4 second, we’re wasting extra time. And those seconds are going to add up.

Read on for a smarter approach. Ideally we’d be able to use asynchronous event handling with awaits for all of this, but the real world is not always so nice.

Mikey Bronowski wants to change workbook properties:

The module’s capability at the moment does not allow to directly update the metadata of the workbook, so we are going to dig a little bit deeper. The properties are hiding behind Workbook.Properties class.

Mikey Bronowski continues a series on using Powershell to modify Excel files:

In this part, we will work on an existing workbook that already has worksheets. If you want to learn how to add new worksheets using the Add-Worksheet have a look at this blog post.

In case you haven’t noticed in the script above we used -MoveToStart switch, that means all the new worksheets were added at the beginning.

Read on for examples around moving sheets to the front or end, moving sheets before or after other sheets, and changing the colors of different tabs.

Greg Moore gives us an overview of the Powershell IDE landscape:

Before I go too deep into this article, I want to distinguish between editing a file and running it. I’m going to focus on editors here, but most development environments include a way to execute a PowerShell script or PowerShell commands. However, do not confuse the editor with the execution environment.

I used the Powershell ISE for a long while, but eventually stopped because its settings were just different enough from the shell’s settings that things which would work just fine in the ISE would fail when I set them up as automated tasks. I don’t remember what those things were, though, so further research may be required. Nowadays, I’ll use VS Code when I need a proper editor and just wing it on the shell for one-off stuff.

Jess Pomfret describes a helpful module:

I was listening to a podcast last week about PowerShell, when one of the hosts mentioned having to ‘up arrow’ back through your history to find a command you wanted to rerun.  This made me realise that I should write this quick post on using PSReadLine’s interactive search function.  This tip is a serious time saver and I rely on it heavily.

The great news is that if you are using Windows PowerShell on Windows 10 or if you’re using PowerShell 6+, PSReadLine is already installed and you can immediately start using this tip.  If you don’t have the module though, it’s easy enough to install from the PowerShell Gallery:
