Lowercase Email Addresses
Trim and lowercase CSV email addresses in place
Clean email addresses in a CSV by trimming surrounding whitespace and converting them to lowercase in place, while preserving the original columns and source lineage.
About this Model
Transforms an uploaded contacts CSV by trimming leading and trailing whitespace from each email address, then converting it to lowercase. The structured “Lowercase Emails” Transform replaces the existing email values in place, keeps only the original name and email columns, and preserves direct lineage to the source CSV. The resulting data remains available to inspect, reuse, and download. Repeated runs reuse the existing Transform, while reset removes generated results without removing the included source or Model structure.
