Single-purpose tools with visible assumptions, evidence, and exportable results.
Format dense X12 EDI into readable, numbered segments in your browser without uploading the document.
Format UN/EDIFACT messages into readable segments with UNA-aware delimiter and release-character handling.
Detect X12 and EDIFACT element, component, segment, repetition, and release characters locally.
Check X12 ISA/IEA, GS/GE and ST/SE or EDIFACT UNB/UNZ and UNH/UNT control pairs and counts.
Count all EDI segments and verify declared X12 SE or EDIFACT UNT transaction counts with visible evidence.
Split X12 ST/SE or EDIFACT UNH/UNT transactions into separate previews and downloads without changing the source.
Compare two EDI documents by normalized segment and element position with local, line-by-line difference evidence.
Convert X12 or EDIFACT segments to explicit JSON with delimiter metadata, positions, elements, and components.
Preview EDI segments as CSV rows with stable position, transaction, tag, and element columns before export.
Redact selected EDI segment values locally while preserving tags, element counts, delimiters, and the original input.
