Spreadsheets to code

CSV is the universal language of spreadsheets and JSON is what web applications speak. This bridges the two, so data moves out of Excel, Google Sheets or a legacy database and into an application without a script in between.

Smart parsing

Unlike a plain string splitter, this handles the CSV edge cases: quoted fields that contain the delimiter, and numbers and booleans detected rather than left as strings, so the JSON does not need cleaning afterwards.

Array of objects, or array of arrays

By default the first row is treated as headers, which produces an array of objects with one key-value pair per row. If your data has no header row, switch it to an array of arrays and the raw structure is kept intact.
