Effortlessly Change Binary File MimeTypes and Extensions
detail.loadingPreview
Automate the process of changing the MIME type and extension of binary files within your n8n workflows. This tool simplifies the manipulation of binary data, ensuring compatibility with downstream services.
About This Workflow
This n8n workflow is designed to provide granular control over binary file data. It allows you to effectively change the perceived MIME type and file extension of any binary input. By converting binary data to a Base64 string and then reconstructing it with a specified filename and extension, this workflow ensures that your files are correctly interpreted by subsequent nodes or external applications. It's an essential tool for scenarios requiring format adaptation or ensuring data integrity across different systems.
Key Features
- Dynamic Binary Property Identification: Automatically detects the incoming binary property name.
- Customizable Output File Naming: Easily set your desired output file name and extension.
- Robust Conversion Logic: Utilizes code and binary extraction for reliable format changes.
- User-Friendly Configuration: Clear instructions and sticky notes guide you through setup.
How To Use
- Configure
SET OUTPUT FILE NAMENode: In theSET OUTPUT FILE NAMEnode, locate theoutput_file_nameparameter. Replace the placeholder textSET YOUR OUTPUT FILE NAME AND EXTENSION !! (ex: .mp3 or .png)with your desired file name and its extension (e.g.,document.pdf,image.png,audio.mp3). The extension is crucial as it dictates the new MIME type. - Review Sticky Notes: The
Sticky Notenodes provide essential guidance. The "CONFIGURE HERE" note reiterates the importance of setting theoutput_file_name. The "Core Logic (No Edit Needed)" note explains the underlying process of extraction and reconstruction, confirming no changes are needed there. - Connect Nodes: Ensure the connections are as per the provided JSON snippet:
Change Binary MimeType/Extension->SET OUTPUT FILE NAME->Extract from File->Change Binary Data Type. - Run Workflow: Execute the workflow with your binary input. The output will be the binary data with the updated file name and MIME type.
