+## Save to File
+
+This component saves [DataFrames, Data, or Messages](/concepts-objects) to various file formats.
+
+1. To use this component in a flow, connect a component that outputs [DataFrames, Data, or Messages](/concepts-objects) to the **Save to File** component's input.
+The following example connects a **Webhook** component to two **Save to File** components to demonstrate the different outputs.
+

+
+2. In the **Save to File** component's **Input Type** field, select the expected input type.
+This example expects **Data** from the **Webhook**.
+3. In the **File Format** field, select the file type for your saved file.
+This example uses `.md` in one **Save to File** component, and `.xlsx` in another.
+4. In the **File Path** field, enter the path for your saved file.
+This example uses `./output/employees.xlsx` and `./output/employees.md` to save the files in a directory relative to where Langflow is running.
+The component accepts both relative and absolute paths, and creates any necessary directories if they don't exist.
+:::tip
+If you enter a format in the `file_path` that is not accepted, the component appends the proper format to the file.
+For example, if the selected `file_format` is `csv`, and you enter `file_path` as `./output/test.txt`, the file will be saved as `./output/test.txt.csv` so the file is not corrupted.
+:::
+5. Send a POST request to the **Webhook** containing your JSON data.
+Replace `YOUR_FLOW_ID` with your flow ID.
+This example uses the default Langflow server address.
+```text
+curl -X POST "http://127.0.0.1:7860/api/v1/webhook/YOUR_FLOW_ID" \
+-H 'Content-Type: application/json' \
+-d '{
+    "Name": ["Alex Cruz", "Kalani Smith", "Noam Johnson"],
+    "Role": ["Developer", "Designer", "Manager"],
+    "Department": ["Engineering", "Design", "Management"]
+}'
+```
+6. In your local filesystem, open the `outputs` directory.
+You should see two files created from the data you've sent: one in `.xlsx` for structured spreadsheets, and one in Markdown.
+```text
+| Name         | Role      | Department   |
+|:-------------|:----------|:-------------|
+| Alex Cruz    | Developer | Engineering  |
+| Kalani Smith | Designer  | Design       |
+| Noam Johnson | Manager   | Management   |
+```
