1. Set up the tables in the UI of input mapping in Keboola
2. Set up the configuration json in the following way:

{ "parameters": { "S3key": "XXXXXXX", "S3secretKey":"XXXXXXXXX", "bucketName":"XXXXXXXXXX" } }

3. The component will then take all the input tables, transforms them into .xlsx files and uploads to S3 accordingly to your json settings.
