+[Richard Kuhnt](https://github.com/r15ch13) wrote the following:
+
+I watched [your video about the CSV conversion](https://youtu.be/7pPN2Ph8eJ0) and that inspired me to write a small PowerShell function to do that.
+
+```pwsh
+# Converts Flipper SubGhz RAW Files to PSCustomObject[]
+function ConvertFrom-SubGhzRAW {
+    param(
+        [Parameter(Mandatory = $true, Position = 0, ValueFromPipeline = $true)]
+        [String] $Path
+    )
+
+    process {
+        $data = Get-Content $Path
+        if(!$data.Contains("Filetype: Flipper SubGhz RAW File")) {
+            throw "$Path is not a Flipper SubGhz RAW File"
+        }
+        $data | Select-Object -Skip 5
+        | ForEach-Object { $_.Replace("RAW_Data: ", "") }
+        | Join-String -Separator " "
+        | Select-String -Pattern '(\d+)\s(-\d+)' -AllMatches
+        | ForEach-Object { $_.Matches }
+        | ForEach-Object { [PSCustomObject]@{ Tone = $_.Groups[1]; Silence = $_.Groups[2] } }
+    }
+}
+```
+
+
+Copy and paste to console hit `<Enter>`, then run:
+
+```pwsh
+# convert one file
+ConvertFrom-SubGhzRAW mysubfile.sub | ConvertTo-Csv | Out-File mycsvfile.csv
+```
+
+```pwsh
+# convert every *.sub file in a directory
+Get-ChildItem *.sub | ForEach-Object { ConvertFrom-Sub -Path $_ | ConvertTo-Csv | Out-File "$($_.BaseName).csv" }
+```
