Frequently Asked Questions
Common questions about CSV to JSON conversion
What's the difference between array and object output formats?
Array format creates a JSON array where each CSV row becomes an object. Object format creates a single JSON object with the first column as keys. Array format is most common for datasets, while object format is useful for key-value mappings.
How does the tool handle different delimiters?
The tool supports comma, semicolon, tab, and pipe delimiters. Choose the delimiter that matches your CSV file format. If your data contains the delimiter character within values, make sure those values are properly quoted in the CSV.
What happens if my CSV has no headers?
If you uncheck "First Row Contains Headers", the tool will generate generic column names like "column1", "column2", etc. You can also manually add headers to your CSV data before conversion for better JSON property names.
Can I convert large CSV files?
Yes, the tool can handle CSV files up to 10MB. For very large files, the conversion might take a few seconds. All processing happens in your browser, so your data remains private and secure.
How are data types handled in the conversion?
By default, all CSV values are converted to strings in JSON. The tool preserves the original text format. If you need specific data types (numbers, booleans), you may need to process the JSON further or ensure your CSV uses appropriate formatting.
What if my CSV contains special characters or quotes?
The tool properly handles special characters, quotes, and Unicode text. CSV values containing commas or quotes should be enclosed in double quotes according to CSV standards. The tool will correctly parse and convert these to valid JSON.
