ConvertCSV

Confirm the delimiter and quoting rules before interpreting a CSV file. Then filter or sort the rows and choose the target representation, such as JSON objects or SQL statements. A table's structure matters as much as its extension: nested JSON and fixed-width records need different conversion routes from a simple spreadsheet export.

The CSV-to-JSON page accepts a file, pasted data or a data-source URL and offers delimiter, header, quoting, field-selection and numeric-string options before download. Nested objects use column-heading conventions, while JSON Lines is a separate output mode. Save Form includes both data and settings, so treat that saved file as a copy of the dataset. The website says ordinary tool processing runs client-side; its hosted API and desktop products are separate routes.
