About the CSV to JSON Converter
The CSV to JSON Converter turns spreadsheet-style CSV data into an array of JSON objects, with one object per row keyed by the column headers. It is useful for importing spreadsheet exports into apps and APIs.
How it works
The first line is read as column headers. Every following line is split on commas, and each value is paired with its header to build an object. Surrounding double quotes are removed from headers and values.

Frequently Asked Questions
Q. Does it handle commas inside quoted values?
Not yet. Values are split on every comma. If your data has commas inside fields, export it with a different separator or clean it first.
Q. Are numbers converted?
All values are kept as strings so that nothing is lost, such as leading zeros in IDs or postcodes.
Q. Is my data uploaded?
No. Conversion happens in your browser.
