## 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.
