Analysts use it to clean and reformat exports before loading into Excel or Sheets. Non-technical users use it to open a JSON file or convert a CSV without writing any code. Most online converters upload your data to their servers. csvjson processes everything locally using JavaScript โ your data never leaves your device. This matters for anyone handling production data, customer records, or anything governed by data privacy policies
