# ConvertFrom-Text

## SYNOPSIS

Convert structured text to objects.

## SYNTAX

### File (Default)

```yaml
ConvertFrom-Text [-Pattern] <Regex> [-Path] <String> [-TypeName <String>]
[-NoProgress] [<CommonParameters>]
```

### Inputobject

```yaml
ConvertFrom-Text [-Pattern] <Regex> [-InputObject] <String>
[-TypeName <String>] [-NoProgress] [<CommonParameters>]
```

## DESCRIPTION

This command will take structured text such as from a log file and convert it to objects that you can use in the PowerShell pipeline. You can specify the path to a text file, or pipe content directly into this command. The piped content could even be output from command-line tools. You have to specify a regular expression pattern that uses named captures. The names will become property names in the custom objects.

The command will write a generic custom object to the pipeline. However, you can specify a custom type name. You might want to do this if you have your own format ps1xml file and want to handle formatting through that file.

## EXAMPLES

### EXAMPLE 1

```powershell
PS C:\> $b = "(?<Date>\d{2}-\d{2}-\d{4}\s\d{2}:\d{2}).*(?<Error>\d+),\s+(?<Step>.*):\s+(?<Action>\w+),\s+(?<Path>(\w+\\)*\w+\.\w+)"
PS C:\> ConvertFrom-Text -pattern $b -path C:\windows\DtcInstall.log

Date   : 10-18-2020 10:49
Error  : 0
Step   : CMsdtcUpgradePlugin::PostApply
Action : Enter
Path   : com\complus\dtc\dtc\msdtcstp\msdtcplugin.cpp

Date   : 10-18-2020 10:49
Error  : 0
Step   : CMsdtcUpgradePlugin::PostApply
Action : Exit
Path   : com\complus\dtc\dtc\msdtcstp\msdtcplugin.cpp
...
```

The first command creates a variable to hold the regular expression pattern that defines named captures for content in the DtcInstall.log. The second line runs the command using the pattern and the log file.

### EXAMPLE 2

```powershell
PS C:\> $wu = "(?<Date>\d{4}-\d{2}-\d{2})\s+(?<Time>(\d{2}:)+\d{3})\s+(?<PID>\d+)\s+(?<TID>\w+)\s+(?<Component>\w+)\s+(?<Message>.*)"
PS C:\> $out = ConvertFrom-Text -pattern $wu -path C:\Windows\WindowsUpdate.log -noprogress
PS C:\> $out | Group-Object Component | Sort-Object Count

In this example, the WindowsUpdate log is converted from text to objects using the regular expression pattern. Given the size of the log file this process can take some time to complete so the progress bar is turned off to improve performance.

### EXAMPLE 3

```powershell
PS C:\> Get-Content c:\windows\windowsupdate.log -totalcount 50 |
ConvertFrom-Text $wu
```

This example gets the first 50 lines from the Windows update log and converts that to objects using the pattern from the previous example.

### EXAMPLE 4

```powershell
PS C:\> $c = "(?<Protocol>\w{3})\s+(?<LocalIP>(\d{1,3}\.){3}\d{1,3}):(?<LocalPort>\d+)\s+(?<ForeignIP>.*):(?<ForeignPort>\d+)\s+(?<State>\w+)?"
PS C:\> netstat | select -skip 4 | ConvertFrom-Text $c |
Format-Table -autosize

TCP      192.168.6.98 50753     74.125.129.125 5222        ESTABLISHED
```

The first command creates a variable to be used with output from the Netstat command which is used in the second command.

### EXAMPLE 5

```powershell
PS C:\> $arp = "(?<IPAddress>(\d{1,3}\.){3}\d{1,3})\s+(?<MAC>(\w{2}-){5}\w{2})\s+(?<Type>\w+$)"
PS C:\> arp -g -N 172.16.10.22 | Select-Object -skip 3 |
ForEach-Object {$_.Trim()} |
ConvertFrom-Text $arp -noprogress -typename arpData

172.16.10.126                     00-0e-58-8c-13-ac                dynamic

...
```

The first command creates a regular expression for the ARP command. The second prompt shows the ARP command being used to select the content, trimming each line, and then converting the output to text using the regular expression named pattern. This example also defines a custom type name for the output.

Type: String
Parameter Sets: File
Aliases: file

Required: True
Position: 1
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
```

### -Pattern

A regular expression pattern that uses named captures. This parameter has an aliases of regex and rx.

```yaml

Parameter Sets: (All)
Aliases: regex, rx

Required: True
Position: 0

### -TypeName

Enter an optional typename for the object output. If you don't use one, the command will write a generic custom object to the pipeline.

```yaml
Type: String
Parameter Sets: (All)
Aliases:

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
```

### CommonParameters

This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutVariable, -OutBuffer, -PipelineVariable, -Verbose, -WarningAction, and -WarningVariable.
