Truncate YAML

How to Use:

• Paste your YAML into the input box or import a .txt, .yaml, or .yml file
• Use the Max string length field to set how many characters each value can be
• Toggle Trim whitespace to remove leading/trailing spaces before truncation
• Click Truncate or just type it updates automatically
• Use Copy Output to copy results to your clipboard
• Use Export to File to download the trimmed YAML as a .txt
• Toggle Maximize output if you’re working with longer files and need more space
• Click Clear All to reset everything including input, output, toggles, and file info

What Truncate YAML can do:

This tool finds the values in your YAML and cuts them off at the length you decide. Whether it’s a long string under a field like description, or a nested string in a list, it keeps the beginning and appends … to show it’s been shortened. It doesn’t affect your YAML keys, spacing, or formatting just trims the values for cleaner viewing. That’s perfect when you want to preview a config file, send a snippet, or build a summary from a large dump. The trim toggle helps clean up messy data, and the max length input gives you full control. And since it’s all client-side, nothing leaves your browser.

Example:

Input:

description: A very long description that might need truncating for preview or storage.

Output (max length 20):

description: A very long descri...

Common Use Cases:

This comes in handy when you’re displaying YAML in a UI and want to avoid overflow, or when you’re debugging and just want to see the start of each value. It’s also great if you’re sanitizing large configs for review, or want to reduce the size of YAML content before saving, logging, or exporting.

Useful Tools & Suggestions:

If you’re chopping down YAML, Minify YAML first to shrink it cleanly before trimming. And for testing how systems handle broken or partial input, Add Errors to YAML can take things a step further.
