Frequently Asked Questions
Is my spreadsheet data uploaded anywhere?
No — everything runs entirely in your browser using JavaScript. Your data is never sent to a server, and closing the tab clears it (use Save as .xlsx or .csv to keep a copy).
Which Excel functions are supported?
Over 100, spanning Math (SUM, ROUND, POWER), Logical (IF, AND, OR, IFERROR), Text (LEFT, CONCATENATE, SUBSTITUTE), Date (DATE, YEAR, DATEDIF), Lookup (VLOOKUP, INDEX, MATCH), Statistical (MEDIAN, STDEV, RANK), and Financial (PMT, FV, NPV).
Can I open a file I already have?
Yes — use the Open button to load an existing .xlsx or .csv file, edit it, and save it back out in either format.
