About this tool
This converter transforms tabular CSV records into a JSON array that is ready for APIs, JavaScript applications, data imports, and configuration work.
Column headings become JSON keys. Empty cells are retained as empty strings so columns do not silently disappear.
The parser recognizes Windows and Unix line endings, quoted commas, and doubled quote escapes. Each header must be present and unique to avoid ambiguous JSON keys.
Frequently asked questions
Does the converter support commas inside CSV fields?
Yes. Fields wrapped in double quotes can contain commas, line breaks, and escaped double quotes.
Is my CSV uploaded?
No. Parsing and JSON generation happen locally in your browser, so the contents are not sent to VCM Suite.
What becomes a JSON property name?
The first CSV row supplies the property names. Each following row becomes one JSON object.
