Open JSONL and NDJSON Data Online

JSON Lines stores one independent JSON value per line, which suits logs and streaming datasets better than one large JSON array. Anyfile reads supported plain, gzip or Zstandard variants through DuckDB-Wasm.

Your file stays on this device

Anyfile reads only the local file you select. Parsing, decoding and rendering happen in this browser tab; the file is not uploaded to Anyfile servers.

What Anyfile can show

  • Inferred columns from newline-delimited records
  • Paged rows from plain or supported compressed JSONL

Limits and conditions

  • Multiline JSON values break the one-record-per-line model
  • Heterogeneous nested objects may not flatten into stable columns

Common question

Are JSONL and NDJSON different formats?

They are commonly used names for the same one-JSON-value-per-line convention, so NDJSON routes here as an alias.
