JSON Merge

Free online merge multiple JSON objects into one JSON array

Tool Guide

Introduction

The online JSON list merge tool can merge a list of JSON entries (one per line) into a single JSON, making it easier to format and parse data.

Sometimes logs are recorded in JSON format, one entry per line, with many logs written to the same log file. This tool can quickly merge all logs into a single log array for easier subsequent parsing and processing.

You can choose whether to skip JSON entries when an error occurs. If you choose to skip, invalid entries are skipped automatically; otherwise, the tool tells you which line has an invalid JSON entry, so you can check and re-merge after correcting it.
