What's new in the JSON hub

Row export formats, SQL-style joins, field statistics, and array utilities joined the JSON hub in recent batches. Pick the output or operation you need instead of scrolling the full grid.

The JSON hub is no longer just format and compare—recent batches added row export formats, SQL-style joins, field-level stats, and array slicing pages. Everything below runs in your browser; start from the output shape you need.

Export JSON rows to flat text

When you have an array of objects and need a file Excel, a log pipeline, or a script can consume, pick the delimiter first.

Join, union, and diff row sets

Field stats, padding, and cleanup

Still start with format, tree, and compare

For the full symptom-first map (repair, JSON5, codegen), see which JSON tool do I need? Export and join neighbors from the GSC cluster batch are also summarized in GSC cluster long-tail guide.

Common use cases

  • Export an API response array to TSV for a spreadsheet without writing a script.
  • Anti-join two id lists to find records missing from a nightly sync.
  • Pad a short fixture array to a fixed length for chart or grid tests.

Common mistakes to avoid

  • Joining arrays without a stable key

    Anti-join and symmetric-diff pages need a shared field name—normalize keys first with rename or pick.

  • Using row export on nested documents

    TSV/CSV exporters expect arrays of flat objects—flatten or pick fields before export.

FAQ

How is this different from the original JSON tools guide?

That guide covers format, compare, and interchange broadly; this page highlights row export, joins, and field stats added in recent hub batches.

Can agents prefill JSON tools?

Many single-input JSON pages accept q or qb for the document body; parameterized field tools may open without URL prefill.
