Needs changes. This template uses 2 thing(s) that n8n 3.0 removes: Read Binary File, Write Binary File. 2 breaking item(s) found. Static check, last run 2026-10-19.

What this workflow does

This workflow has 18 nodes and runs manually, when you click “Execute workflow”. It uses only n8n's built-in nodes.

How it runs

Trigger: Manually, when you click “Execute workflow”.

  1. Setup - Define file paths (Edit Fields (Set)): sets 2 fields: path_to_converter, project_file
  2. Create - Excel filename (Edit Fields (Set)): sets 3 fields: xlsx_filename, path_to_converter, project_file
  3. Check - Does Excel file exist? (Read Binary File): uses Read Binary File
  4. If: checks a condition and branches into true / false
  5. Info - Skip conversion (Edit Fields (Set)): sets 2 fields: status, xlsx_filename
  6. Extract - Run converter (Execute Command): runs a shell command on the n8n host
  7. Merge: merges the data from its input branches
  8. Check - Did extraction succeed? (If): checks a condition and branches into true / false
  9. Read Project Excel File (Read Binary File): uses Read Binary File
  10. Set Validation Rules Path (Edit Fields (Set)): sets 1 field: validation_rules_path

…plus 7 more steps. See the full node list below.

Before you upgrade to n8n 3.0

2 things in this workflow are removed in n8n 3.0. Fix them before you upgrade:

  • Read Binary File in Read Project Excel File, Read Validation Rules File, Check - Does Excel file exist?: replace with Read/Write Files from Disk.
  • Write Binary File in Save Validation Report1: replace with Read/Write Files from Disk.

Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).

Removed in 3.0Replace with
Read Binary File
Read Project Excel File, Read Validation Rules File, Check - Does Excel file exist?
Read/Write Files from Disk
Write Binary File
Save Validation Report1
Read/Write Files from Disk
