JSON to Table

User lists and order lists are easier to scan as a table than as raw JSON.

Paste an array, click To table, and the right pane shows text you can copy into a doc.

Columns come from object keys. Missing keys leave empty cells. Deep nesting is not split into multiple tables.

Preview stays local. Convert to CSV when you need Excel.

Where columns come from

Keys that appear on objects are collected. Extra fields on later rows join the header; earlier rows stay blank in those cells.

This is not a pivot

No sort, filter, or charts. Export CSV for analysis. This page answers "how many columns do I have?"

How to use it

  1. Paste a JSON array. Prefer flat objects.
  2. Click To table.
  3. Scan columns for empty values and obvious misalignment.
  4. Use the CSV page if someone else needs to edit it.
  5. If nesting is heavy, flatten first or inspect one record in Tree view.

When to use it

  • Scan an API list for missing fields.
  • Paste a sample array into a requirements doc.
  • Preview columns before you export.
  • Compare with a Batch mock result: do ten rows look alike?

Keep in mind

  • A single object is readable, but Tree view is a better fit.
  • Static text table — no interactive sort.
  • Nothing is uploaded.

FAQ

Does it have to be an array?

An object array works best. A single object is readable, but Tree view is a better fit.

How is column order decided?

Keys are collected in the order they appear. Clean the sample if you need a fixed column set.

Can I sort or filter?

This page is a static preview. Export CSV for real pivots.

Is it uploaded?

No.

How are nested objects shown?

Usually as text or a JSON snippet. They are not split into child tables.

What about an empty array?

There are no rows to show. Confirm you pasted a list, not a wrapper object.

How does this work with CSV convert?

Preview here; import or export files there.

Will alignment look off?

Monospace text can shift with mixed scripts. Trust columns, not spaces.
