Tabular Data Round-Trip Differ

Most workflows only export. This one goes both ways. Import a CSV, TSV, or JSON table, edit any cell, then get a canonical cell-wise diff, the modified file back in the same format, and SHA-256 content hashes for the input and the output. It is a working demo of the OpenChainGraph import binding and write-back diff, the lens get/put round trip: an untouched table reproduces byte-for-byte, and every change is captured as a signed, replayable delta.

⚠ Prototype demonstrating bidirectional import and write-back for OpenChainGraph. Canonicalization here is intentionally simple (trim, sorted keys, values as text). It illustrates the round-trip and hashing model; it is not yet the full normative import-binding profile.

Content hashes are computed with the browser SubtleCrypto SHA-256 over a simple canonical form and are for demonstration — the normative import-binding canonicalization is still being specified.

Paste CSV, TSV, or a JSON array of objects (or load a file). The first row is the header for CSV/TSV.
