+---
+
+# Improve the DSC accessibility of output in PowerShell
+
+Most terminal environments only display raw text. Users that rely on screen readers are faced with
+tedious narration when consuming large amounts of raw text because the raw output doesn't have the
+accessibility metadata to characterize the format of the content.
+
+There are two ways to improve the accessibility of the output in PowerShell:
+
+- Output the data in a way that it can be viewed in another tool that supports screen reading
+  technologies.
+- Reduce the amount of output displayed in the terminal by filtering and selecting the data you
+  want and output the text in a more readable format.
+
+## Display the data in a tool outside of the terminal
+
+For large amounts of data, rather than output to the host, consider writing output in a format that
+can be viewed in another tool that supports screen reading technologies. You might need to save the
+data to a file in a format that can be opened in another application.
+
+### Out-GridView command on Windows
+
+For small to moderate size output, use the `Out-GridView` command. The output is rendered using
+Windows Presentation Foundation (WPF) in tabular form, much like a spreadsheet. The GridView
+control allows you to sort, filter, and search the data, which reduces the amount of data that
+needs to be read. The GridView control is also accessible to screen readers. The **Narrator** tool
+built into Windows is able to read the GridView details, including column names and row count.
+
+The following example shows how to display a list of DSC resources in a GridView control.
+
+```powershell
+dsc resource list | ConvertFrom-Json | Out-GridView
+```
+
+The following example shows how to display a list of DSC adapted resources in a GridView control.
+
+```powershell
+dsc resource list -a Microsoft.Windows/WindowsPowerShell |
+    ConvertFrom-Json |
+    Out-GridView
+```
+
+The `Out-GridView` command is only available in PowerShell on Windows.
+
+### Character Separated Value (CSV) format
+
+Spreadsheet applications such as **Microsoft Excel** support CSV files. The following example shows
+how to save the output of a command to a CSV file.
+
+```powershell
+dsc resource list | ConvertFrom-Json | Export-Csv -Path .\myFile.csv
+Invoke-Item .\myFile.csv
+```
+
+The `Invoke-Item` command opens the file in the default application for CSV files.
+
+### HyperText Markup Language (HTML) format
+
+HTML files can be viewed by web browsers such as **Microsoft Edge**. The following example shows
+how to save the output of a command to an HTML file.
+
+```powershell
+dsc resource list | ConvertFrom-Json | ConvertTo-HTML | Out-File .\myFile.html
+Invoke-Item .\myFile.html
+```
+
+The `Invoke-Item` command opens the file in your default web browser.
+
+## Reduce the amount of output
+
+One way to improve the accessibility of the output is to reduce the amount of output displayed in
+the terminal. PowerShell has several commands that can help you filter and select the data you
+want.
+
+### Select and filter data
+
+Rather than returning a large mount of data, use commands such as `Select-Object`, `Sort-Object`,
+and `Where-Object` to reduce the amount of output. The following example gets the list of Windows
+PowerShell DSC resources that manage processes on the computer.
+
+Each of the following commands improves the output in a different way:
+
+- The `Where-Object` command reduces the number of items returned by filtering the list to only
+  show resources that have the word `process` in their type name.
+- The `Select-Object` command selects only the resource type name, kind, and version.
+- The `Format-List` command displays the output in list format, which provides a better narration
+  experience for screen readers.
+
+```powershell
+dsc resource list -a Microsoft.Windows/WindowsPowerShell |
+    ConvertFrom-Json | 
+    Where-Object {$_.type -like "*process*" } |
+    Select-Object -Property Type, Kind, Version |
+    Format-List
+```
