Frequently Asked Questions
What CSV format is supported?
Standard CSV with comma separators. The first row must be headers. Quoted values with commas inside are handled correctly.
How are empty values handled?
Empty values in your CSV become empty strings in the JSON output. If you need null values instead, you'll need to process the JSON further.
What about CSV files with semicolons?
This tool expects comma separators. Replace semicolons with commas before converting, or use a text editor's find-and-replace feature.
