  • -Trim: This parameter is used to specify whether or not the whitespace around the string data should be trimmed.
  • -AllowEmpty: This parameter is used to specify whether or not empty values should be allowed in the output.
  • -AllowDuplicateKeys: This parameter is used to specify whether or not duplicate keys should be allowed in the output.
  • -ErrorAction: This parameter is used to specify the action that should be taken if an error occurs.
  • -ErrorVariable: This parameter is used to specify the variable that should be used to store any errors that occur.
  • -OutVariable: This parameter is used to specify the variable that should be used to store the output of the command.
  • -OutBuffer: This parameter is used to specify the size of the output buffer.
  • -Verbose: This parameter is used to specify whether or not verbose output should be displayed.
  • -Debug: This parameter is used to specify whether or not debug output should be displayed.
  • -WarningAction: This parameter is used to specify the action that should be taken if a warning occurs.

Inputs

The ConvertFrom-StringData command takes a string of data as its input. This string of data should be in the form of key-value pairs, separated by a delimiter. For example, the following string of data could be used as input for the ConvertFrom-StringData command:

Name=John;Age=30;Gender=Male

In this example, the delimiter is the semicolon (;), and the key-value pairs are Name=John, Age=30, and Gender=Male.

Outputs

The output of the ConvertFrom-StringData command is a hash table. This hash table contains the key-value pairs that were specified in the input string of data. For example, the output of the ConvertFrom-StringData command for the input string of data above would be a hash table containing the following key-value pairs:

  • Name: John
  • Age: 30
  • Gender: Male

Examples

The following examples demonstrate how to use the ConvertFrom-StringData command:

  • To convert a string of data into a hash table, use the following command:

ConvertFrom-StringData -StringData “Name=John;Age=30;Gender=Male”

  • To convert a string of data into a hash table, and specify a custom delimiter, use the following command:

ConvertFrom-StringData -StringData “Name=John|Age=30|Gender=Male” -Delimiter “|”

  • To convert a string of data into a hash table, and trim the whitespace around the string data, use the following command:

ConvertFrom-StringData -StringData “Name=John;Age=30;Gender=Male” -Trim

Tips

When using the ConvertFrom-StringData command, there are a few tips to keep in mind:

  1. Be sure to specify the correct delimiter when using the -Delimiter parameter.
  2. Use the -Trim parameter to trim the whitespace around the string data.
  3. Use the -AllowEmpty and -AllowDuplicateKeys parameters to control how empty values and duplicate keys are handled.
  4. Use the -ErrorAction, -ErrorVariable, -OutVariable, -OutBuffer, -Verbose, -Debug, -WarningAction, and -WarningVariable parameters to customize the output.
  5. Use the -WhatIf and -Confirm parameters to control whether or not the command should be run in “What If” mode or prompt for confirmation before running.
