Frequently Asked Questions
Can I upload large CSV spreadsheets safely?
Yes! All CSV parsing and data operations execute entirely in your local browser memory using JavaScript Web Workers and typed streams. Your sensitive business spreadsheets, customer lists, and financial records are never sent to external servers.
How does the CSV to JSON conversion handle quotation marks and commas?
Our CSV engine adheres strictly to RFC 4180 standards, correctly handling escaped quotation marks, embedded commas within quotes, multi-line field values, and empty columns.
Can I extract specific columns from a CSV file?
Yes! The CSV Column Extractor allows you to choose any column header (such as Emails, Phone Numbers, or User IDs) and copy or export all values as a clean line-separated list.
How does the duplicate row remover compare rows?
You can perform exact row matching or case-insensitive deduplication, eliminating duplicate customer records or redundant log entries while preserving first-seen row ordering.
