AWS DynamoDBtoCSV

This application will export the content of a DynamoDB table into a CSV (Comma delimited value) output. All you need to do is create a config.json file in that same directory where you configure your accessKeyId, secretAccessKey and region as such:

{
    "accessKeyId": "REPLACE",
    "secretAccessKey": "REPLACE",
    "region": "REPLACE"
}

The output is comma separated and each field is enclosed by double quotes ("). Double quotes in the data as escaped as "

Usage

typically, to use you'd run:

node dynamoDBtoCSV.js -t Hourly_ZEDO_Impressions_by_IP > output.csv

to export to CSV

Use -d to describe the table prior so you can have an idea of the number of rows you are going to export

node dynamoDBtoCSV.js -t Hourly_ZEDO_Impressions_by_IP -d

to get some information about the table.

Full syntax is:

node dynamoDBtoCSV.js --help
