Excel & Data

CSV to JSON

Preview your data, choose columns, and download the converted file.

1. Add your data

Maximum input: 10 MiB. Processing takes place on the server. Temporary workspaces are deleted after each response; abandoned workspaces are removed by recovery cleanup after six hours.

2. Configure and preview

Output and data options

Text values stay text by default. After preview, select, rename, order, or explicitly type columns. Dates use yyyy-MM-dd; timestamps require an ISO 8601 offset. Nested collections remain JSON text in a cell.
