What is JSON for Chat?
This tool formats JSON into ```json code blocks sized for chat platforms. It auto-chunks large JSON across multiple messages to respect Slack's 3000-char and Discord's 2000-char limits.
How it works
The JSON is formatted and wrapped in code fences. If the output exceeds the platform's message limit, it intelligently splits at newline boundaries into multiple complete message blocks.
- Paste JSON. Paste your JSON data.
- Choose platform. Select Slack or Discord for the correct character limit.
- Copy chunks. Copy each message chunk and paste into your chat.
Examples
Share an API response
Format a 5KB API response into 2 Slack messages for your team channel.
Common mistakes
Very large JSON
JSON exceeding 10+ chunks is better shared as a file attachment.
Alternatives
File upload
For very large JSON, upload as a .json file instead.
Frequently asked questions
Does it truncate my data?
No — all data is preserved across multiple complete message chunks.
