What is JSON to DynamoDB?
JSON to DynamoDB is a utility that converts standard JSON into the specific "DynamoDB JSON" format required by the AWS SDK and CLI. It handles the explicit type descriptors (like {"S": "value"} for strings or {"N": "123"} for numbers) that DynamoDB uses.
Why use JSON to DynamoDB?
DynamoDB's native JSON format is verbose and difficult to write by hand. This tool allows you to take clean, standard JSON and instantly convert it into the format DynamoDB expects, making it much easier to work with the AWS CLI or SDKs.
How to use JSON to DynamoDB
Paste your standard JSON object. The tool will generate the DynamoDB-compatible JSON with all the necessary type markers.
Example Output
{
"id": { "N": "1" },
"name": { "S": "John Doe" },
"email": { "S": "john@example.com" },
"isActive": { "BOOL": true },
"tags": { "L": [{ "S": "admin" }, { "S": "dev" }] }
}Common Errors & Troubleshooting
Unsupported types
Fix: Ensure your JSON data only contains types supported by DynamoDB (Strings, Numbers, Binary, Booleans, Nulls, Sets, Lists, and Maps).
Size limits
Fix: DynamoDB has a 400KB item size limit; ensure your JSON object stays within this bound.
