How the text is read
How the JSON is written
Leading zeros, phone numbers and very long IDs stay text so nothing is corrupted.
user.name becomes {"user":{"name":…}}
Otherwise the last value wins and earlier ones are lost.
If any cell in a column has to stay text, the whole column does — so code reading it never hits two types.
Everything runs on your device — nothing is uploaded. Values that look numeric but would lose precision as JSON numbers, such as long IDs, are deliberately kept as text.
