Common Questions
Can I save my progress?
Since we value privacy, we don't store your files on our servers. However, you can use our "Export" feature to download your edited CSV at any time and resume later by re-uploading the new file.
Is there a row limit?
Our CSV editor is built on top of high-performance libraries that can handle hundreds of thousands of rows depending on your device's memory.
What happens to my data?
Nothing. Your data stays in your browser. As soon as you close the tab, all session data is permanently erased from your RAM.
