Connectors: bring in a tool you already use — What comes across, and what doesn't
Most field types map straight over: text, long text, email, URL, phone, number, currency, percent, rating, checkbox, dates (including their times), and both kinds of select with their options. Airtable's primary field becomes both the record's name and its first field. Two things that used to arrive as text are real now: links between tables are rebuilt as RowFold relations, matched on Airtable's own record ids, and attachments are downloaded into RowFold's own storage during the import — which matters, because the file links Airtable hands out expire within hours.
Two things still arrive as text, each with a warning saying so:
• Formulas, rollups and lookups, as the value they had computed to — the expression itself doesn't travel. Rebuild the ones you need in RowFold's own formula and rollup editors; the warnings list every column that needs it.
