Frequently Asked Questions
Does the CSV cleaner handle different delimiters?▾
The cleaner uses RFC 4180 parsing which handles standard comma-separated values, including quoted fields with commas inside them.
How does deduplication work?▾
The CSV Deduper compares rows based on the columns you select. You can choose to compare all columns or specific ones for smarter deduplication.
Can I convert nested JSON to CSV?▾
Yes. The JSON to CSV tool supports optional nested object flattening using dot-notation, so nested properties become separate columns.
