Requirements and limitations for structured and freeform document processing in SharePoint

The following sections outline key factors to consider when planning to use a structured or freeform document processing model.

Structured document processing

Icon	Description
	Supported file types This model supports the following file types: see file type requirements.
	Supported languages This model supports the following languages: see Model for Fixed-template documents.
	OCR considerations This model uses optical character recognition (OCR) technology to scan .pdf files, image files, and .tiff files. OCR processing works best on documents that meet these requirements.
	Optimization tips If your model isn't performing as you want it to, try these steps to improve the performance of your model.
	Multi-Geo environments When setting up Syntex in a Microsoft 365 Multi-Geo environment, you can only configure it to use the model type in the central location. If you want to use this model type in a satellite location, contact Microsoft support.
	Custom Power Platform environments If you use a custom environment (rather than the default environment) for Power Platform processing, there are additional setup requirements. For more information, see Custom Power Platform environments.
	Multi-model libraries If two or more trained models are applied to the same library, the file is classified using the model that has the highest average confidence score. The extracted entities are from the applied model only. You can have only one freeform or one structured model per library.
