Format Details

.opml

OPML

OPML (Outline Processor Markup Language) is an XML-based format designed for exchanging hierarchical outline and list structures between applications. It is most commonly used to export and import RSS/Atom feed subscription lists between news readers and podcast apps. OPML also serves as a portable format for structured notes, project outlines, and hierarchically organized content in productivity tools.

.yaml

YAML

YAML (YAML Ain't Markup Language) is a human-friendly data serialization format designed to be more readable than JSON or XML for configuration files and structured data. It uses indentation and minimal punctuation to represent nested data structures, sequences, and mappings in a way that closely resembles natural language. YAML is the native configuration format for Kubernetes, Docker Compose, GitHub Actions, Ansible, and countless other modern developer tools.

Converting OPML to YAML: what actually changes

OPML to YAML is one of the conversions this site performs, but the two formats are not interchangeable containers. Here is what the file keeps, what it loses, and how to get a result you can use.

What .OPML and .YAML each hold

.OPML is a document format built for reading, printing or circulating a document, storing text, layout, fonts and images. .YAML is a data format built for analysing, importing or exchanging records, storing rows, columns and value types. Converting between them is a decision about which of those two jobs the result needs to do.

What changes when categories differ

The file is parsed and its contents are written out as structured data for analysing, importing or exchanging records. Everything that could be extracted from the source lands in the output; formatting and styling that have no equivalent in .YAML are left behind.

When this conversion is the right one

Reach for .YAML when you need a file for analysing, importing or exchanging records, starting from reading, printing or circulating a document. If that is not what you are after, check what else .OPML converts to before committing to this target.

Tips for a clean OPML to YAML conversion

1

Start from the original file

Convert the .OPML you started with, not an earlier .YAML output. Every extra round trip costs quality and can accumulate formatting drift.

2

Check the real type, not the extension

Text/x-opml becomes application/x-yaml. If a file was renamed rather than converted, it will fail to open — rename it back to its true extension before uploading and the conversion will recognise it.

3

Long documents convert as pages

Page-based output renders one page at a time. Split very large .OPML files first if you only need a specific section — it is faster and keeps the result easy to work with.

4

Limits worth knowing

Uploads are capped per file (30 MB, or 100 MB for video) and processed temporarily — nothing is kept as a permanent copy. For huge document files, split or compress the source first.
