Frequently Asked Questions

How does the converter handle CSV data types?

Our converter automatically detects numbers, booleans (true/false), and null values in your CSV data and converts them to proper JSON types instead of leaving everything as strings.

What CSV delimiters are supported?

We support comma (,), tab, semicolon (;), and pipe (|) delimiters. The tool auto-detects the delimiter, or you can specify it manually for accuracy.
