# Document Processing > Process documents on the server with ServerTextControl: create, load and convert, format text, tables and images, fields, forms, comments, changes and pages. - **Product:** TX Text Control .NET Server - **Section:** Documentation - **Kind:** Topic - **Path:** TX Text Control .NET Server > Document Processing - **1453 words** - **Web URL:** https://docs.textcontrol.com/tx-text-control-dotnet-server/document-processing/ - **LLMs URL:** https://docs.textcontrol.com/tx-text-control-dotnet-server/document-processing/llms.txt - **LLMs-Full URL:** https://docs.textcontrol.com/tx-text-control-dotnet-server/document-processing/llms-full.txt --- Reports generated overnight, contracts converted to PDF, uploads checked before they're stored: document processing happens on the server, in code, without a user interface. `ServerTextControl` creates, loads, changes, converts and saves documents in console applications, services and ASP.NET Core, with a part of its API for each element of a document, from text and paragraphs to tables, images, fields, form fields, comments and tracked changes. If you haven't used `ServerTextControl` yet, start with [Getting Started: Document Processing](https://docs.textcontrol.com/tx-text-control-dotnet-server/getting-started/document-processing/llms-full.txt). The [ServerTextControl](https://docs.textcontrol.com/tx-text-control-dotnet-server/overview/components/servertextcontrol/llms-full.txt) page in the Overview explains what the component is and where it runs. ### How You Work With Documents on the Server Code that processes a document goes through the same steps: 1. **Create an instance** of `ServerTextControl` and call `Create`. 2. **Get the document**: create it from pieces, or load it from a file, a byte array or a string. 3. **Change the document** through the collections of `ServerTextControl`: `Selection` and `Paragraphs` for text, `Tables`, `Images`, `TextFrames`, `HeadersAndFooters`, `Sections`, `FormFields`, `Comments`, `TrackedChanges` and the other collections for the other elements. 4. **Save the result** in the format you need, to a file, a byte array or a string, and dispose the instance. The examples use the Core package `TXTextControl.TextControl.Core.SDK`, which runs on Windows and Linux. The code is the same with the Classic package `TXTextControl.TextControl.ASP.SDK`, which only runs on Windows. Where the two differ, as for printing, page images, XML documents and the DOC format, the difference is noted. ### Find the Right Page | If you want to | Read | |---|---| | Create and dispose
