Frequently asked questions
Which JSON structures are accepted?
Arrays of objects (the usual API shape), arrays of arrays, and single objects (converted to key-value pairs).
What about nested values?
Nested objects and arrays are serialized as JSON inside their cell, so no information is lost.
What if my objects have different keys?
Columns are the union of all keys; missing values become empty cells.
Can I paste sensitive data?
Yes: the conversion is 100% local, nothing is sent to any server.
