Good to know
The honest limits, before you spend time on it
Values stay text
Numbers, dates and true or false are written exactly as they appear, as text, so nothing is reinterpreted on the way.
Rows that don't fit
A row with more or fewer cells than the header waits in Needs Review instead of being guessed at.
Checked before it's shown
The JSON is read back and compared with the table, cell by cell, before it's offered.
Limits
Up to 1,000,000 characters of text, or a text file up to 2 MB.
Beyond this one task
Give AMGlide the text. It works out the rest.
Smart Drop reads what you brought and suggests what fits — then carries it into the next step without asking for it again.
