  "account": "The Data Studio from OnePassApps converts CSV files into JSON format while maintaining the original string format for every value. For instance, the number 42.5 appears as the string \"42.5\", and the boolean value true remains as the string \"true\". An empty cell converts to an empty string, rather than a null value. This conservative approach ensures the conversion is usually accurate, but it can catch users off guard.\n\nTo convert a CSV to JSON, users can access the Data Studio, navigate to the \"To JSON\" tab, and either paste or drop a CSV file into the panel. Clicking the \"Convert CSV to JSON\" button initiates the conversion process. The converted rows appear in a generated output block, which is then available for download as either a CSV or a JSON file.\n\nDuring the conversion, the tool retains the exact capitalization of boolean values (true, false, TRUE) and preserves leading zeros in strings. However, it does not infer data types or convert dates, ensuring the output JSON remains faithful to the original CSV. Additionally, any formulas present in the CSV are converted to strings, making them inert in the resulting JSON file.",

Every value comes out as a JSON string . The number 42.5 comes out as the string \"42.5\" . The word true comes out as the string \"true\" . An empty cell comes out as an empty string, not null . That is a conservative choice, and for a converter it is…",
