Common questions
Are comparisons case-sensitive?
No by default. Tick the Aa box on a condition to make that one case-sensitive.
How do numeric comparisons treat empty or non-numeric cells?
They never match. An empty cell will not satisfy 'less than 5' — without that guard every blank row would pass, since an empty string converts to zero.
Is my file uploaded anywhere?
No. The file is parsed and processed entirely in your browser using JavaScript. It never leaves your device, and nothing is stored on our servers.
