Q: What file types can the Read Binary Files node handle?

The node reads any file type as binary data — PDFs, images (PNG, JPG, TIFF), Office documents (XLSX, DOCX), CSVs, ZIP archives, audio files, and anything else stored on the filesystem. What happens next depends on the downstream nodes: n8n has dedicated nodes for extracting data from spreadsheets, reading PDFs, decompressing archives, and converting between formats.

Q: Can this node watch a folder for new files and process them automatically?

Not on its own — the Read Binary Files node reads files when the workflow runs, but it does not watch for changes. To get automatic processing, we pair it with a Schedule Trigger that runs the workflow every few minutes. The workflow checks the folder, reads any new files, processes them, and moves the originals to an archive folder to prevent double-processing.

Q: How do you handle large files without crashing n8n?

For large files (over 50-100MB), we configure n8n's memory limits appropriately and process files one at a time rather than loading a batch into memory simultaneously. For very large files, we may split the processing across multiple workflow executions or use streaming approaches where possible. We also set up monitoring to alert on memory usage spikes.

Q: Can you extract data from PDFs or images read by this node?

Yes. Once the file is loaded into the workflow as binary data, we can pass it to OCR services (for scanned documents or images), AI models (for intelligent data extraction), or n8n's built-in PDF and spreadsheet nodes (for structured files). The extracted data is then routed to your database, CRM, or accounting system.

Q: Can you set up a file processing pipeline for our business?

Yes, this is a core part of what we do. We build end-to-end pipelines in n8n that read files from a source (local folder, SFTP, email attachment, cloud storage), extract and validate the data, and push it into your business systems. The pipeline includes error handling, duplicate detection, and audit logging so you have full visibility into what was processed and when.

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

About Read Binary Files

The Read Binary Files node in n8n reads files from the local filesystem in binary format — images, PDFs, spreadsheets, ZIP archives, or any other file type — and passes the binary data into the workflow for processing by subsequent nodes. It is the starting point for any n8n workflow that needs to work with files stored on the server rather than files received via API or webhook.

Common use cases include reading invoice PDFs for data extraction, loading image files for processing or upload to another service, picking up CSV exports dropped into a folder by a legacy system, and reading configuration files needed by other workflow steps. The node supports wildcard patterns to read multiple files at once and can be combined with a schedule trigger to poll a directory for new files on a regular interval.

At Osher, we use the Read Binary Files node as part of file processing pipelines built in n8n. A typical build might watch a shared folder for new documents, read them with this node, extract text using AI or OCR, classify the document type, and route the extracted data to the right system — a CRM, accounting package, or database. If your team is manually downloading, opening, and re-entering data from files, our automated data processing services can replace that manual work with an n8n pipeline that handles it automatically.

Frequently Asked Questions

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

What file types can the Read Binary Files node handle?

Can this node watch a folder for new files and process them automatically?

How do you handle large files without crashing n8n?

Can you extract data from PDFs or images read by this node?

How does this differ from the HTTP Request node for getting files?

The Read Binary Files node reads files from the local filesystem (the server where n8n is running). The HTTP Request node downloads files from remote URLs. If your files are on the same server as n8n (e.g., in a shared folder, mounted drive, or local directory), use Read Binary Files. If they are hosted on a remote server or cloud storage API, use HTTP Request or the relevant cloud storage node.

How it works

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

As Read Binary Files 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 Files with integrate and automate 800+ tools.

Step 1

Document Your Current File Handling Process

We map out how files currently arrive (shared folder, email, SFTP, manual download), what your team does with them (open, read, copy data into another system), and where the data ultimately needs to go. This tells us exactly what the automated pipeline needs to replicate.

Step 2

Design the File Processing Pipeline

Based on the process map, we design the n8n workflow: which trigger starts it (schedule, webhook, or manual), how files are read and validated, what data extraction method is used (parsing, OCR, AI), where the extracted data is sent, and how processed files are archived or cleaned up.

Step 3

Configure File Access and Permissions

We set up the file paths, folder permissions, and any network mounts needed for the Read Binary Files node to access your files. If files come from SFTP or cloud storage, we configure those connections too. All credentials are stored securely in n8n’s credential manager.

Step 4

Build the Extraction and Routing Logic

We build the workflow nodes that process the binary files — extracting text from PDFs, parsing spreadsheet rows, running OCR on images, or using AI to classify and extract structured data. The extracted data is then mapped to the fields in your target system and pushed via API.

Step 5

Add Error Handling and Duplicate Detection

We implement checks that catch malformed files, missing data, and files that have already been processed. Failed files are moved to an error folder with a log entry, and your team is notified so they can investigate. This prevents bad data from entering your systems silently.

Step 6

Test with Real Files and Go Live

We run the pipeline against a batch of real files from your environment, verify every file is processed correctly, and confirm the extracted data lands in the right places. Once validated, we activate the scheduled trigger and monitor the first few days of production runs.
