More information about the DeepL API can be found here: https://www.deepl.com/de/docs-api/introduction/. To use this PowerShell function, a DeepL ApiKey is needed which requires an account. To register for an account, go to www.deepl.com. .LINK https://github.com/admins-little-helper/DeeplTranslate .LINK https://www.deepl.com .LINK https://www.deepl.com/de/docs-api/introduction/ #> function Invoke-DeeplTranslateFile { <# .SYNOPSIS Translates a file using the DeepL API. .DESCRIPTION The 'Invoke-DeeplTranslateFile' function allows to translate a file using the DeepL API. Supported file types are .docx, .pptx, .pdf, .htm, .html, .txt. .PARAMETER InputFile The file path to the document to translate. Only these types are supported: .docx, .pptx, .pdf, .htm, .html, .txt. .PARAMETER OutputPath The folder path in which the output file should be saved. The output filename will be set to '<InputFilename>_<TargetLanguage>.<FileExtension>'. .PARAMETER TargetLanguage The language the text should be translated to. .PARAMETER OpenTranslatedFile If specified, the output file will be opened after download. In case there are more than 5 input files from pipeline ipnut, only the first 5 files will be opened. In case there are more than 5 input files specified via parameter, no file will be opened automatically. .PARAMETER Force If specified, existing output files will be overwritten. .PARAMETER SourceLanguage Language of the text to be translated. If no source language is specified, the DeepL Api tries to automatically detect the language. .PARAMETER Formality Sets whether the translated text should lean towards formal or informal language. .PARAMETER GlossaryId Specify the glossary to use for the translation. Important: This requires the SourceLanguage parameter to be set and the language pair of the glossary has to match the language pair of the request. .PARAMETER ApiKey API authentication key. You need an authentication key to access the DeepL API. Refer to the DeepL API documentation for more information. .EXAMPLE Invoke-DeeplTranslateFile -InputFile C:\Temp\SourceDoc.docx -OutputPath C:\Temp\Output -SourceLanguage "EN" -TargetLanguage "DE" -ApiKey "<MyApiKey>" This example shows how to translate a DOCX document. .EXAMPLE Invoke-DeeplTranslateFile -InputFile C:\Temp\SourceDoc.docx -OutputPath C:\Temp\Output -SourceLanguage "EN" -TargetLanguage "DE" -ApiKey "<MyApiKey>" -OpenTranslatedFile This example shows how to translate a DOCX document and directly opens the output file once it has been successfully downloaded. .EXAMPLE Invoke-DeeplTranslateFile InputFile C:\Temp\SourceDoc.docx -OutputPath C:\Temp\Output -SourceLanguage "EN" -TargetLanguage "DE" -ApiKey "<MyApiKey>" This example shows how to translate multiple files. .EXAMPLE Invoke-DeeplTranslateFile -InputFile C:\Temp\SourceDoc.docx -OutputPath C:\Temp\Output -SourceLanguage "EN" -TargetLanguage "DE" -ApiKey "<MyApiKey>" -Force This example shows how to translate multiple files, overwriting any existing files in the output path. .INPUTS System.IO.FileInfo for parameter 'InputFile' .OUTPUTS System.IO.FileInfo for each output file generated. .NOTES Author: Dieter Koch Email: diko@admins-little-helper.de .LINK https://github.com/admins-little-helper/DeeplTranslate/blob/main/Help/Invoke-DeeplTranslateFile.txt #> [CmdletBinding()] param ( [ValidateScript({ # Check if the given path is valid. if (-not (Test-Path -Path $_) ) { throw "File or folder does not exist" } # Check if the given path is a file (not a folder). if (-not (Test-Path -Path $_ -PathType Leaf) ) { throw "The Path argument must be a file.
