DynamoDB to SQL Converter Online — Convert DynamoDB Operations to SQL Queries

Paste your DynamoDB params JSON above and get the equivalent SQL query instantly. Handles FilterExpression, ExpressionAttributeNames, typed attribute values, and all CRUD operations — everything runs in your browser.

How to Convert DynamoDB to SQL — Step-by-Step

Step 1

Input Your DynamoDB Params

Got a DynamoDB params object you need to understand as SQL? Three ways to load it:

•
Paste directly: Copy the DynamoDB params JSON from your code and paste it in — conversion happens instantly
•
Upload a file: Click "Upload" to select a .json or .js file
•
Load a sample: Click "Sample" to see a DynamoDB Scan with FilterExpression converted to SQL

Example: DynamoDB Scan Params

Here is a typical DynamoDB Scan params object you might want to understand as SQL:

{
  "TableName": "users",
  "FilterExpression": "#status = :statusVal",
  "ExpressionAttributeNames": {
    "#status": "status"
  },
  "ExpressionAttributeValues": {
    ":statusVal": { "S": "active" }
  },
  "Limit": 25
}
Step 2

Automatic Conversion to SQL

The converter parses your DynamoDB API params and generates readable SQL:

•
Resolves placeholders: ExpressionAttributeNames (#name) and ExpressionAttributeValues (:value) are replaced with actual column names and values
•
Converts functions: DynamoDB-specific contains(), begins_with(), and attribute_exists() become familiar SQL LIKE and IS NOT NULL
•
Extracts types: DynamoDB typed values like {"S": "active"} become SQL-friendly 'active'

Example: SQL Output

The DynamoDB params from Step 1 converted to SQL:

SELECT *
FROM users
WHERE status = 'active'
LIMIT 25;
Step 3

Copy or Download Your SQL Query

When it looks right, grab it:

•
Copy to clipboard: One click — paste into your SQL client, documentation, or migration script
•
Download as file: Save as a .sql file
•
Try other converters: Convert the same query to MongoDB, or go back from SQL to DynamoDB. You can also format the SQL output for even cleaner results.

Frequently Asked Questions — DynamoDB to SQL

How do I convert DynamoDB to SQL online?

Paste your DynamoDB params JSON into the input editor and the converter generates the equivalent SQL query instantly. It handles Scan, Query, PutItem, UpdateItem, and DeleteItem. No account needed.

What DynamoDB operations does the converter support?

Scan and Query operations become SELECT, PutItem becomes INSERT INTO, UpdateItem becomes UPDATE SET, and DeleteItem becomes DELETE FROM. It resolves ExpressionAttributeNames, ExpressionAttributeValues, FilterExpression, ProjectionExpression, and Limit.

Why would I need to convert DynamoDB to SQL?

Common reasons include: understanding legacy DynamoDB code written by someone else, migrating from DynamoDB to a relational database, documenting existing queries in a more universal format, or simply understanding what a complex FilterExpression actually does in plain SQL terms.

Does it handle DynamoDB contains() and begins_with()?

Yes. DynamoDB contains(field, value) becomes SQL field LIKE '%value%', and begins_with(field, prefix) becomes field LIKE 'prefix%'. Similarly, attribute_exists() becomes IS NOT NULL.

Is my data safe?

Your DynamoDB params are processed entirely in your browser — nothing is sent to any server. The conversion is 100% client-side.

Is this DynamoDB to SQL converter free?

Completely free, no account needed, no limits. Also check out our other NoSQL tools: SQL to MongoDB, MongoDB to SQL, SQL to DynamoDB, and MongoDB to DynamoDB.
