Word Automation Service is a part of SharePoint 2010. Word Automation Service is available in the Standard edition and in the Enterprise edition. It is a feature of SharePoint 2010, so SharePoint 2010 should be purchased and installed to use Word Automation Services.

For Word Automation Services Architecture refer http://msdn.microsoft.com/en-us/library/ee556832.aspx.

The following concepts are basic for Word Automation Services:

Conversion
Conversion Job
Document Queue

Conversion:

Conversion in Word Automation Services is a process of converting the word document to other formats. For example converting .doc file format to .pdf format. It constitutes of the following steps:

Create a conversion job
ConversionJob job = new ConversionJob("Word Automation Services");
Set the desired output file format
job.Settings.OutputFormat = SaveFormat.PDF;
Add files to the conversion job
AddFile () method:
Syntax:
job.AddFile(string inputFile, string outputFile)
Example:
job.AddFile("http://serverName:31829/sites/Home/Shared%20Documents/ArticleLinks.docx", "http://serverName:31829/sites/Home/Shared%20Documents/ArticleLinks.pdf")

AddFolder () method:

Syntax:
job.AddFolder(SPFolder inputFolder, SPFolder outputFolder, bool recursion);
Example:
job.AddFolder("\Shared Documents\Word ocuments", "\Shared Documents\PDF Documents", false);

AddLibrary () method:

Syntax:
job.AddFile(SPList inputList, SPList outputList)
Example:
job.AddFile("Word Library", "Document Library");
Submit the job to the document queue
job.Start();

Conversion Job:

Conversion job describes the files to be converted and the operation to perform on them.

Each file is considered to be a conversion item, and the conversion item will be mapped to Conversion job. Conversion job contains one or more conversion items.

Document Queue:

Document Queue is a "first in, first out", which is used to start the conversion and that schedule can be set in the conversion job.

Using API you can convert the word documents into different formats. There are three main methods that are used for server side document conversions.

AddFile()
AddFolder()
AddLibrary()

For AddFile() method refer http://www.c-sharpcorner.com/UploadFile/anavijai/4816/
For AddFolder() method refer http://www.c-sharpcorner.com/UploadFile/anavijai/4823/
For AddLibrary() method refer http://www.c-sharpcorner.com/UploadFile/anavijai/4822/

Using powershell you can use Word Automation Service application to convert the word document into other formats. Refer http://www.c-sharpcorner.com/UploadFile/anavijai/4820/ and http://www.c-sharpcorner.com/UploadFile/anavijai/4801/Default.aspx.
