How to send a json object pretty printed as an email python

Question

I have a python script that gets a cluster health as json and sends me a mail. The issue is that the json is not pretty printed.
These are the methods I have tried already:

Simple –> json.dumps(health)
json.dumps(health, indent=4, sort_keys=True)

But the output in gmail is still unformatted, somewhat like this

{ "active_primary_shards": 25, "active_shards": 50, "active_shards_percent_as_number": 100.0, "cluster_name": "number_of_pending_tasks": 0, "relocating_shards": 0, "status": "green", "task_max_waiting_in_queue_millis": 0, "timed_out": false, "unassigned_shards": 0 }

Mail was sent to gmail

I can’t say for certain, but it would seem like your email-sending code is defaulting to sending an “HTML” email, and in HTML consecutive spaces collapse into one, that way HTML code like:

<p>
    This is a paragraph, but it's long so
    I'll break to a new line, and indented
    so I know it's within the `p` tag, etc.
</p>

Looks like “This is a paragraph, but it’s long so I’ll break to a new line, and indented so I know it’s within the p tag, etc.” to the user.

So, I’d say your two options are:

Change the email sending code to send the Content-type header as text/plain, or
Replace all your spaces with the   (non-breaking space) character and newlines with <br> (breaks), for example:
```
email_body = json.dumps(
    health, indent=4, sort_keys=True).replace(' ', '&nbsp;').replace('n', '<br>')
```

>>> import json
>>> s = json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=4)
>>> print s
{
    "4": 5, 
    "6": 7
}

mine works fine

maybe it’s version related, post your version and output

The suggested solutions did not work for me. I tried json pretty printed into a variable and I see the email with expected json pretty format.

import json, pprint
body=json.dumps(message, indent=4) 
pprint.pformat(body, indent=4) # pprint body but assign the output to body variable instead of printing to console. This will introduce new line and other expected characters in the message string body. 
body=body.replace("n","<br/>") # I just replaced new line with <br/>
message = MIMEText(body, "HTML") # create an MIME message and send the body to intented email recepient.
