What is YAML Parser?
Ever looked at a wall of YAML and wished you could just see it as a table? That's what this tool does. YAML Parser takes your YAML (YAML Ain't Markup Language) and turns it into interactive HTML tables you can actually work with.
Whether you're debugging a configuration file, analyzing data exports, or trying to make sense of a CI/CD pipeline config, this tool saves you time. No more manually parsing through nested structures or writing scripts just to view your data. YAML is widely used for configuration files, Docker Compose, Kubernetes manifests, and more, and the parser handles all standard YAML structures.
The best part? Everything runs in your browser. Your data never touches our servers unless you explicitly share it. It's fast, free, and private.
How to Use the YAML Parser
Follow these steps to parse YAML into interactive tables. Each step uses the actual buttons and panels on this page.
Paste, Upload, or Load Sample
Paste YAML into the left editor, or click Upload to load a file. Click Sample to see example telecomm subscriber YAML. Example:
subscribers:
- subscriberId: SUB-1001
plan: Unlimited 5G
dataUsage: 45.2
status: active
carrier: Verizon
- subscriberId: SUB-1002
plan: Family Plan
dataUsage: 120.5
status: activeWatch It Transform
The table appears on the right. Arrays become rows, properties become columns. Nested data gets expandable tables. Parsing follows the YAML 1.2 specification.
Filter and Edit
Type in the filter boxes at the top of each column to narrow results. Click Edit and double-click any cell to fix values. Changes sync back automatically.
Export to Excel
Click Download to save as .xls for Excel or Google Sheets. All processing runs in your browser.
When You'd Actually Use This
Docker Compose Files
Trying to understand a complex Docker Compose configuration? Paste it here and see all your services, volumes, and networks in a clear table format. Much easier than scrolling through nested YAML.
Kubernetes Manifests
Need to review Kubernetes deployment configs or compare multiple resources? View them as tables to see the structure clearly. Filter by labels, annotations, or any property.
CI/CD Configuration
Debugging GitHub Actions workflows or GitLab CI configs? Paste your YAML and see all jobs, steps, and environment variables in an organized table. Spot missing configurations instantly.
Config File Reviews
Trying to understand a complex YAML config or settings file? View it as a table to see the structure clearly. Edit values directly if you need to make changes. Way easier than hunting through nested indentation.
Common Questions
Do you store my YAML data?
No. Everything runs in your browser using JavaScript. Your YAML never leaves your computer. We process all data locally to ensure your information stays private and secure.
What YAML formats work?
Anything that's valid YAML according to the YAML 1.2 specification. Arrays, objects, nested structures, anchors, aliases, multi-line strings – all of it. Complex nesting just creates more nested tables.
Can I edit the data?
Yes. Click "Edit" and double-click any cell. Change the value, hit Enter, and it updates automatically. You can also remove columns entirely if you don't need them. It's like editing a spreadsheet, but your YAML structure stays intact.
How does filtering work?
Type in the boxes at the top of each column. It filters rows that contain your search term in that column. You can filter multiple columns at once – it shows rows that match all your filters. Case-insensitive, so "sub" finds "SUB" too.
What can I export to?
Right now, Excel (.xls format). Opens in Excel, Google Sheets, LibreOffice – basically any spreadsheet app. The table structure stays intact, so nested data becomes nested tables in Excel too.
How big can my YAML file be?
No hard limit, but performance depends on your browser. Small files (under 1MB) parse instantly. Files around 5MB might take a second or two. Really huge files (10MB+) can slow things down, but they'll still work.
Other YAML Tools You Might Need
This parser is great for viewing data, but sometimes you need other things. Here are our other tools that work well together:
