Mongo Query Formatter
Beautify Mongo-style query snippets so operators, selectors, and pipelines are easier to read.
What is Mongo Query Formatter?
Make JSON-shaped MongoDB query text easier to inspect. Mongo shell expressions with constructors or unquoted keys are JavaScript-like syntax, not necessarily valid JSON.
How to use Mongo Query Formatter?
Step 1
Paste the Mongo query or pipeline snippet.
Step 2
Run the formatter to improve spacing and indentation.
Step 3
Copy the output into docs, PR comments, or debugging notes.
Example input / output
Inspect {"status":"active","total":{"$gte":100}} before comparing it with a query using $gt. Formatting makes the operator visible; it does not decide which operator is correct.
Example input
db.orders.find({status:'active',$or:[{total:{$gt:100}},{priority:true}]},{email:1,total:1})Check the result
- Custom shell helpers and invalid JavaScript-like syntax may require manual cleanup.
- This tool formats structure but does not validate query semantics.
Practical developer examples
Inspect operator placement
Check whether an operator applies to a field, an array element or the whole document. A readable query can still select unexpected records.
Verify Extended JSON
ObjectId and date representations vary between shell syntax and Extended JSON. Confirm the exact representation your driver accepts.
Common developer use cases
No database request or explain plan is run. Shell-specific snippets may be formatted on a best-effort basis or require a JSON-compatible representation.
Common issues
FAQ
Will this execute my query?
No. It formats text only.
Does readable formatting prove the query is efficient?
No. Use explain output, indexes and representative data to assess execution.
