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.
What Makes This Tool Different
Real Tables, Not Just Formatting
Most YAML viewers just prettify the code. This one actually converts structures into rows and properties into columns. Nested data? Gets its own expandable table. It's like having Excel for YAML.
Edit Right in the Table
Found a typo? Double-click and fix it. Changes sync back automatically. No copy-paste, no manual editing – just click and type. Works great for quick data fixes.
Search Without Scripts
Type in any column header to filter rows instantly. Need to find all items with a specific property? Just type it in. No need to write scripts or grep through files.
Go Fullscreen
Click maximize and the table takes over your screen. Perfect when you're dealing with wide datasets or need to show data to someone. All the filtering and editing works there too.
Export to Excel
One click downloads your table as an .xls file. Open it in Excel, Google Sheets, or any spreadsheet app. Handy when you need to do pivot tables or share data with non-developers.
Works with All YAML Formats
Supports arrays, objects, nested structures, anchors, aliases, and more. Perfect for Docker Compose files, Kubernetes manifests, GitHub Actions workflows, and any YAML configuration.
How It Works
Paste Your YAML
Grab YAML from anywhere – your config file, Docker Compose, Kubernetes manifest, GitHub Actions workflow, or database export. Paste it in the left editor. Not sure what YAML looks like? Click "Sample" to see an example. The editor provides syntax highlighting, so you'll spot errors quickly.
Watch It Transform
As soon as you paste, the table appears on the right. Arrays turn into rows, properties become columns. Got nested data? It shows up as tables within tables. The parsing follows the YAML 1.2 specification, so it handles everything standard YAML supports.
Filter and Fix
Type in the filter boxes at the top of each column to narrow down results. Need to fix a value? Click "Edit" and double-click any cell. The change shows up immediately. It's like editing a spreadsheet, but your YAML structure stays intact.
Export or Analyze
Download as Excel if you need to work with it in Microsoft Excel or Google Sheets. Everything runs client-side – fast and private.
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?
Nope. Everything runs in your browser using JavaScript. Your YAML never leaves your computer. We follow the same privacy principles as tools like JSON Formatter – process locally, keep it private.
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 "john" finds "John" 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:
