What happens to CSV rows with missing values?

Columns missing a value in a row produce null in the JSON output. If the CSV has an empty field (two consecutive commas), the converter inserts an empty string or null depending on the tool setting.

How does the converter handle quoted CSV fields?

Quoted fields (surrounded by double quotes) can contain commas and newlines without being split. The converter strips the quotes and preserves the content as a string value.

Can I convert CSV with a non-comma delimiter?

Yes. Tab-separated (TSV) and semicolon-delimited files are common in European locales. The converter has a delimiter setting to handle any single-character separator.

Convert CSV to JSON Array

CSV is the most common export format for spreadsheets and databases, while JSON is the universal format for web APIs and application data. Converting CSV to JSON makes tabular data consumable by JavaScript applications without needing a CSV parsing library in production. The converter uses the first row as property names and maps each subsequent row to a JSON object. Columns with numeric values are cast to numbers automatically; boolean columns (true/false) are converted to JSON booleans.

Example

id,name,email,role,active,score
1,Alice Johnson,[email protected],admin,true,98.5
2,Bob Smith,[email protected],user,true,72.0
3,Carol White,[email protected],user,false,85.3
4,David Brown,[email protected],moderator,true,91.0
5,Eve Davis,[email protected],user,true,67.8
