1. First create a free account, then simply upload your CSV file by clicking +New > File Upload > Browse to select a file from your machine. Zip large files to save time uploading. Alternatively, you can import JSON from cloud storage like Google Drive, OneDrive, or AWS S3.
2. Next your JSON file will automatically process and flatten to a spreadsheet. For exceptionally large files you'll see a loading bar while the file parses.
3. Once complete, click on the file name in your Library to view the CSV file online. The viewer will open a spreadsheet in a new browser tab for viewing. Here you can filter, search, or create pivot tables with your CSV.
