Q: What does the Read Binary File node do in n8n?

It reads a file from the local filesystem where n8n is running and loads it into the workflow as binary data. You provide the full file path (e.g., /data/incoming/report.csv), and the node makes that file available to subsequent nodes for processing, conversion, or forwarding to other systems.

Q: What types of files can the Read Binary File node handle?

Any file type. The node reads files at the binary level, so it works with CSVs, Excel spreadsheets, PDFs, images, JSON files, XML files, text files, and any other format. What happens next depends on which downstream nodes you use to process the binary data (Spreadsheet File, Convert to/from Binary Data, HTTP Request for uploading, etc.).

Q: Does the file path need to be hardcoded or can it be dynamic?

The file path can be dynamic. You can use n8n expressions to construct the path from variables, dates, or data from previous nodes. For example, you might read from /data/incoming/{{$now.format('yyyy-MM-dd')}}/report.csv to pick up a file from a date-stamped directory. This is useful for processing files that arrive in organised folder structures.

Q: Does Read Binary File work with n8n Cloud or only self-hosted?

Read Binary File accesses the local filesystem of the machine running n8n. On self-hosted deployments (Docker, bare metal, VM), it can read any file the n8n process has permission to access. On n8n Cloud, local filesystem access is restricted. For cloud deployments, use cloud storage nodes (Google Drive, S3, Dropbox) to read files instead.

Q: Can Osher build file processing pipelines for our business?

File processing automation is one of our most common project types. We build pipelines that pick up files from directories, SFTP servers, email attachments, and cloud storage, then process, validate, transform, and load the data into your target systems. See our data processing services or read how we automated patient data entry for a real-world example.

We can help you automate your business with Read Binary File and hundreds of other systems to improve efficiency and productivity. Get in touch if you’d like to discuss implementing Read Binary File.

About Read Binary File

The Read Binary File node in n8n reads a file from the local filesystem of the machine where n8n is running and loads it into the workflow as binary data. You specify the file path, and the node makes that file available for downstream processing by other nodes. It is the starting point for any workflow that needs to work with files stored on the n8n server.

This node is most relevant for self-hosted n8n deployments where your n8n instance has access to a local or mounted filesystem. If files land on a shared drive, a mounted network volume, or a specific directory on your server (from an SFTP upload, a cron job, or another application), Read Binary File picks them up and brings them into your n8n workflow for processing.

At Osher, we use Read Binary File in data processing pipelines where files arrive on the server from external sources. A typical setup involves a partner system dropping CSV files into a directory via SFTP. The n8n workflow uses an Interval trigger to check the directory periodically, Read Binary File to load any new files, and then processes them through conversion, validation, and database insertion steps. We also use it for reading configuration files, loading email templates, and accessing locally stored reference data.

For workflows that need to read files from cloud storage (Google Drive, S3, Dropbox), you would use those platform-specific nodes instead. Read Binary File is specifically for files on the local filesystem. Our n8n team can help you design file processing workflows regardless of where your files are stored.

Frequently Asked Questions

Common questions about how Read Binary File consultants can help with integration and implementation

What does the Read Binary File node do in n8n?

What types of files can the Read Binary File node handle?

Does the file path need to be hardcoded or can it be dynamic?

Does Read Binary File work with n8n Cloud or only self-hosted?

How do I process files from an SFTP drop directory?

A common pattern is: use the Interval or Cron node to trigger the workflow on a schedule, use a Function node to list files in the drop directory, use Read Binary File to load each file, process the contents (parse CSV, extract data, validate), then move or delete the processed files to prevent reprocessing. Alternatively, you can use the SFTP node to read files directly from a remote SFTP server.

How it works

We work hand-in-hand with you to implement Read Binary File

As Read Binary File consultants we work with you hand in hand build more efficient and effective operations. Here’s how we will work with you to automate your business and integrate Read Binary File with integrate and automate 800+ tools.

Step 1

Process Audit

We document your current file-based data flows: which systems produce files, where those files are stored, what happens to them next (manual processing, import into another system), and how often new files arrive. We map file types, naming conventions, and directory structures.

Step 2

Identify Automation Opportunities

We identify file processing tasks that can be automated: files sitting in directories waiting for manual pickup, data that gets manually copied from files into databases or applications, and file format conversions done by hand. We prioritise by frequency, volume, and the business cost of delays.

Step 3

Design Workflows

We design n8n workflows that use Read Binary File to pick up incoming files, convert and parse them into structured data, apply validation and transformation logic, and deliver the processed output to destination systems. We include file tracking (processed vs pending) to prevent duplicate processing.

Step 4

Implementation

We build the workflows in n8n, configure Read Binary File with the correct paths and permissions, set up the trigger schedule, and connect downstream processing nodes. We configure the n8n Docker container or server with the appropriate filesystem mounts and file permissions.

Step 5

Quality Assurance Review

We test with real files from your system, verifying that the workflow reads files correctly, handles edge cases (empty files, locked files, permission errors, unexpected formats), and processes data accurately. We confirm that processed files are properly tracked or archived.

Step 6

Support and Maintenance

After deployment, we monitor file processing success rates and handle issues like filesystem permission changes, directory restructuring, or changes in file formats from source systems. We adjust file paths and parsing logic as your infrastructure evolves.
