Content After YAML ... Document End – Start a New Document

Local only

The ... marker explicitly ends a YAML document. Additional content needs a new document start instead of continuing as though the previous document were still open.

How to fix content after a YAML document end marker

The sample closes the service document with ... and then immediately starts another mapping. Because the first document ended explicitly, the parser needs a new document boundary before more YAML content can follow. This tool is free to use. No account or payment is required.

What you can do here

  • YAML 1.2 parser validation
  • Duplicate mapping key detection
  • Preloaded broken YAML example
  • Readable parser feedback
  • .yaml and .yml file import
  • Browser-local processing

Steps

  1. Locate the ... marker before the parser error.
  2. Decide whether the following content should continue the same document or start another one.
  3. Remove the end marker or insert a new --- start as appropriate, then validate the stream again.

Three dots are an explicit YAML document end

Unlike ordinary line breaks, ... tells the parser that the current document is finished. Later content therefore needs to participate in a new document rather than silently extending the previous one.

Check whether your application accepts YAML streams at all

Even when multiple YAML documents are syntactically separated correctly, many configuration consumers expect exactly one document. Syntax validation and application-level document-count requirements are separate checks.

YAML content after explicit document end

Start a new document before the other mapping after the ... marker.

Common questions

Frequently asked questions

What does ... mean in YAML?

It is the explicit document end marker and tells the parser that the current YAML document is finished.

Can YAML contain content after ...?

Yes in a stream, but the next content needs to start a new document rather than continue the document that was explicitly ended.

Do I need ... at the end of every YAML file?

No. YAML documents commonly end at end-of-file without an explicit ... marker.
