FAQ

Which JSON shapes are supported?

Arrays of objects, arrays of arrays, arrays of values, flat key-value objects and column-oriented objects.

What happens to nested objects?

They are flattened into dotted column names so nothing is silently dropped.

Is there a row limit?

There is no hard row limit, but files above 10 MB are rejected to keep the tab responsive.
