Question 1

Can I insert multiple fields at different positions in one operation?

Accepted Answer

Yes — specify one reference node and multiple new field names (comma-separated) to insert them all after that reference point. Original structure, nesting, and field order are preserved intact.

Question 2

What online tool can batch-add fields to JSON?

Accepted Answer

This tool batch-inserts new fields into every object in a JSON array at a specified position (after a given field). Supports inserting multiple fields (comma-separated) — no scripting needed.

Question 3

Will inserting fields mess up JSON ordering?

Accepted Answer

No. The tool strictly preserves original field order with new fields inserted precisely after the specified position. Existing key-value pairs and nesting are completely unaffected.
