How to use this tool
- 01
Paste enough text to include ISA or UNA/UNB.
- 02

- 03
Confirm the character values and evidence against the source.
02 / Useful for
Common use cases
- Diagnosing nonstandard partner delimiters
- Preparing a parser configuration
- Finding why a compact payload will not split

Assumptions & limitations
Assumptions
- X12 ISA fixed positions are authoritative when a complete ISA is present.
- UNA defines EDIFACT service characters when present.
Limitations
- Short fragments without headers can only be inferred heuristically.
- A detector cannot prove that every segment uses the same delimiters.
04 / FAQ
Questions about delimiter detector
Why does confidence show “inferred”?
The sample did not contain a complete authoritative ISA or UNA header, so recurring separators were scored heuristically.
Can a newline be a segment separator?
Yes. The fallback detector can recognize line-oriented input, though line endings are usually presentation added after parsing.
