Convert CSV to JSON
Convert CSV to JSON in seconds with this free online CSV to JSON converter
CSV (Comma Separated Values) files are the most common format for storing tabular data. Values in a row are separated by commas and rows are separated by newlines.
CSQ files often start with a header row that has column names, but this is not required.
Each row in a CSV file must have the same number of values as the header row.
CSV files do no enforce types or a schema. This means that each column can have multiple types, which can make analysis difficult and compression inefficient.
Parquet files can be easier to analyze and compress better than CSV files.
JSON files do not have a schema or required columns. Each row can have different field names and types. This can
make JSON files difficult to analyze.
