Tool usage guide
The YAML File Merger is a powerful utility designed to consolidate multiple YAML configuration files into a single, unified document using customizable merging strategies.
Background
Managing separate YAML files for base settings and production-specific overrides.
Problem
Manually copying keys between files is error-prone and slow.
How to use
Upload the base.yaml and prod.yaml files, then select 'Deep Merge' to combine them.
Merge Strategy: Deep Merge; Conflict Resolution: OverwriteOutcome
A single production-ready YAML file containing all base settings with production overrides applied.
Background
Multiple team members maintain separate YAML files defining API endpoints.
Problem
Need to combine these lists into one master registry without duplicating entries.
How to use
Upload all endpoint files and select 'Concatenate' or 'Merge Unique' for the array strategy.
Array Handling: Merge UniqueYes, you can upload and merge up to 5 YAML files simultaneously.
Deep merge recursively combines nested objects, while shallow merge only updates top-level keys.
It combines arrays from multiple files and removes any duplicate entries to ensure a clean list.
You can choose to overwrite the existing value, keep the first value encountered, or stop the process with an error.
No, files are processed in memory and are not stored permanently on our servers.
Outcome
A unified registry file containing all unique API endpoints from all contributors.
