How to Format MongoDB Queries Online — Step-by-Step

Step 1

Input Your MongoDB Query

Got a messy MongoDB query from your mongosh shell, application logs, or a code review? Three ways to load it:

•
Paste directly: Copy the query and paste it in — formatting happens instantly
•
Upload a file: Click "Upload" to select a .js or .json file
•
Load a sample: Click "Sample" to see a complex aggregation pipeline formatted

Example: Unformatted MongoDB Query

Here is what a compact MongoDB aggregation pipeline looks like before formatting:

db.orders.aggregate([{$match:{status:"completed",total:{$gte:100}}},{$group:{_id:"$customer_id",totalRevenue:{$sum:"$total"},orderCount:{$sum:1}}},{$sort:{totalRevenue:-1}},{$limit:10}])
Step 2

Automatic Formatting & Validation

No button press needed — the formatter runs the moment you paste:

•
Structured indentation: Each pipeline stage, nested object, and array element gets proper indentation
•
Syntax highlighting: MongoDB operators ($match, $group, etc.), keys, and values are color-coded
•
Error detection: Missing commas, unmatched brackets, and invalid syntax are flagged immediately

Example: Formatted Output

The same query, now properly formatted:

db.orders.aggregate([
  {
    "$match": {
      "status": "completed",
      "total": { "$gte": 100 }
    }
  },
  {
    "$group": {
      "_id": "$customer_id",
      "totalRevenue": { "$sum": "$total" }
    }
  },
  ...
])
Step 3

Copy or Download Your Formatted Query

When it looks right, grab it:

•
Copy to clipboard: One click — paste into your MongoDB shell, Compass, or code editor
•
Download as file: Save as a .js file
•
Minify: Click "Minify" to compress the query into a single line — useful for scripts
•
Convert it: Convert to SQL, DynamoDB, or try our JSON Formatter for the query body

Frequently Asked Questions — MongoDB Query Formatter

How do I format a MongoDB query online?

Paste your MongoDB query into the input editor and the formatter runs instantly — proper indentation, syntax highlighting, and error detection. No account, no button to click, nothing to install.

All of them — find(), aggregate(), insertOne(), insertMany(), updateOne(), updateMany(), deleteOne(), deleteMany(), and plain JSON filter objects. Aggregation pipelines with any number of stages are fully supported.

Does it detect syntax errors?

Yes — missing commas, unmatched brackets, unquoted operators, trailing commas — the formatter catches them. It shows you what went wrong so you can fix it. For SQL query errors, try our SQL Formatter.
