How to Convert SQL Queries to MongoDB Filters

Use the SQL to MongoDB converter to translate WHERE clauses and queries into MongoDB filter objects.

Tool Used

SQL to MongoDB

Open tool
1

Enter your SQL query

Paste a full SELECT statement or just the WHERE clause into the input field. The converter focuses on the filter logic and ignores SELECT columns.

2

Review the operator mappings

The output shows the MongoDB filter object with standard operator translations: = becomes $eq, != becomes $ne, IN becomes $in, and AND/OR become $and/$or arrays.

3

Copy the find() call

The output includes a ready-to-use db.collection.find() call. Copy it directly into your application code or the MongoDB shell.

4

Check LIKE pattern conversions

SQL LIKE patterns translate to $regex. Review the generated regex for correctness and adjust case-sensitivity (the $options: 'i' flag) if your query requires case-insensitive matching.

5

Handle complex queries manually

JOINs, subqueries, and aggregate functions are not supported — these require MongoDB's $lookup aggregation pipeline, which you will need to write by hand.

All done!

You are ready to use SQL to MongoDB like a pro.
