Frequently Asked Questions
What is OPML format?
OPML (Outline Processor Markup Language) is an XML format for outlines. It's commonly used for exchanging outlines between different applications, such as feed readers, mind mapping tools, and outline processors.
Is my data secure?
Yes, all conversion happens in your browser. Your files are never uploaded to any server, ensuring complete privacy and security of your data.
How are CSV columns converted to OPML?
The converter automatically creates OPML outlines based on your CSV structure. The first column typically becomes the main outline items, while subsequent columns create nested outlines or attributes.
Can I convert multiple files at once?
Yes, you can select and convert multiple CSV files simultaneously. Each file will be converted into a separate OPML document.
