What it does

CSV exports from spreadsheets and BI tools are useful — until you need to feed them into a JSON-based pipeline. This tool parses CSV and emits a JSON array of objects, with the first row used as keys.

Numeric and boolean columns are auto-typed (so "true" becomes the boolean true, "42" becomes the number 42). Strings stay strings.

Frequently asked

My data has weird delimiters (tabs, semicolons).

Replace them with commas in the input first, or run a quick Find/Replace pass before pasting.
