Free CSV and JSON tools

Browser tools built on the SvGrid data grid. Files are read and parsed in your browser and never uploaded.

• CSV Viewer - Open a CSV file in your browser, sort, filter and edit it like a spreadsheet, then save it as CSV, JSON or Excel. Free, no sign-up, nothing uploaded.
• JSON to Table - Paste JSON or drop a .json file and see it as a sortable, filterable table. Nested objects become columns; download the result as CSV. Free and private.
