+## File Support
+
+### Overview
+The AskUI Python SDK supports the use of various file formats.
+
+**Supported File Formats**
+- PDF Files (.pdf)
+- Excel Files (.xlsx, .xls)
+- Word Files (.docx, .doc)
+- CSV Files (.csv)
+
+**Model Compatibility Matrix**
+
+| File Format         | AskUI Gemini | Anthropic Claude | Google Gemini
+| ------------------- | ------------ | ---------------- | ----------
+| PDF (.pdf)          | ✅           | ❌               | ✅
+| Excel (.xlsx, .xls) | ✅           | ✅               | ✅
+| Word (.docx, .doc)  | ✅           | ✅               | ✅
+
+**General Limitations**
+- **Processing Model Restriction**: not all models support all document formats
+- **No Caching Mechanism**: All document files are re-processed on every `get()` call
+- **Performance Impact**: Multiple documents mean multiple processing operations per run
+
+
+### 📄 PDF Files (.pdf)
+
+- **MIME Types**: `application/pdf`
+- **Maximum File Size**: 20MB
+- **Processing Method**: **Depends on Usage Context**
+
+
+**Processing Workflow for PDF Files:**
+```mermaid
+graph TD
+    A[Call agent.get with PDF] --> B[Load as PdfSource]
+    B --> C[Send directly as binary to Gemini]
+    C --> D[Gemini processes content]
+    D --> E[Return results directly]
+    E --> F[No storage - process again for next call]
+```
+
+**PDF-Specific Limitations**
+
+- **20MB file size limit** for PDF files
+
+### 📊 Excel Files (.xlsx, .xls)
+
+- **MIME Types**:
+  - `application/vnd.openxmlformats-officedocument.spreadsheetml.sheet` (.xlsx)
+  - `application/vnd.ms-excel` (.xls)
+
+
+```mermaid
+graph TD
+    A[Call agent.get with Excel] --> B[Load as OfficeDocumentSource]
+    B --> C[Convert to Markdown using markitdown - NO AI]
+    C --> D[Process with Gemini]
+    D --> E[Return results directly]
+    E --> F[No storage - convert again for next call]
+```
+
+**Features**:
+- Sheet names are preserved in the markdown output
+- Tables are converted to markdown table format
+- Optimized for LLM token usage
+- Deterministic conversion process (same input = same output)
+
+**Excel-Specific Limitations**
+
+- **file size limit** depending on the model that is used
+- Conversion quality depends on [`markitdown`](https://github.com/microsoft/markitdown) library capabilities
+- Complex formatting may be simplified during markdown conversion
+- Embedded objects (charts, complex tables) may not preserve all details
+- **No AI in conversion**: Conversion is deterministic and rule-based, not AI-powered
+
+### 📝 Word Documents (.doc, .docx)
+
+- **MIME Types**:
+  - `application/vnd.openxmlformats-officedocument.wordprocessingml.document` (.docx)
+  - `application/msword` (.doc)
+**Processing Workflow for Word Documents:**
+
+```mermaid
+graph TD
+    A[Call agent.get with Word] --> B[Load as OfficeDocumentSource]
+    B --> C[Convert to Markdown using markitdown - NO AI]
+    C --> D[Process with Gemini]
+    D --> E[Return results directly]
+    E --> F[No storage - convert again for next call]
+```
+
+**Features**:
+- Layout and formatting preserved as much as possible
+- Tables converted to HTML tables within markdown
+- Deterministic conversion process (same input = same output)
+
+**Word-Specific Limitations**
+
+- **file size limit** depending on the model that is used
+- Conversion quality depends on [`markitdown`](https://github.com/microsoft/markitdown) library capabilities
+- Complex formatting may be simplified during markdown conversion
+- Embedded objects (charts, complex tables) may not preserve all details
+- **No AI in conversion**: Conversion is deterministic and rule-based, not AI-powered
+
+### 📈 CSV Files (.csv)
+
+- **Status**: **Not directly supported**
+- CSV files are treated as regular text content by the LLM
+
+**CSV-Specific Limitations**
+
+- **No specialized CSV parsing**: No structure preservation
+- **Text-only processing**: Treated as regular text content by the LLM
+
+
+### Usage Examples
+
+```python
+from askui import ComputerAgent
+
+with ComputerAgent() as agent:
+    # PDF
+    result = agent.get("Summarize the main points", source="document.pdf")
+
+    # Excel
+    result = agent.get("Extract the quarterly sales data", source="sales_report.xlsx")
+
+    # Word
+    result = agent.get("Extract all action items", source="meeting_notes.docx")
+```
