Pick a tool from the sidebar or a popular chip above. Switch anytime without reload.
Download the result or jump to a related studio with your file still loaded.
Grouped like the sidebar — click to open directly.
No — workbooks autosave locally in your browser via IndexedDB.
Import CSV or previously exported JSON workbooks; native .xlsx is not supported yet.
SUM, AVERAGE, MIN, MAX, COUNT, COUNTA, IF, ROUND and basic cell arithmetic.
