Question 1

What CSV format does this tool accept?

Accepted Answer

Standard RFC 4180 CSV: comma-separated values, first row as headers, quoted fields for values containing commas or newlines. Tab-separated values (TSV) can also be processed by selecting the tab delimiter option. UTF-8 encoding is recommended.

Question 2

What does the output JSON structure look like?

Accepted Answer

By default, the tool produces an array of objects where each object's keys are the CSV header names. For example: [{"name":"Alice","country":"US"},{"name":"Bob","country":"UK"}]. This is the most widely compatible format for APIs and databases.

Question 3

How does the tool handle empty fields?

Accepted Answer

Empty CSV cells become empty strings ("") in JSON by default. Some tools convert them to null. If your data pipeline requires null for missing values, you can post-process the output with a JSON find-and-replace.
