Free AI CSV Data Cleaner: Fix and Transform Datasets Online
Messy, dirty data causes errors when running models, analysis, or seeding databases. The **Sylvaera CSV and JSON Cleaner** audits your columns, highlights quality scores, formats phone/dates, normalizes capitalization, trims trailing spaces and removes duplicates.
By leveraging AWS Bedrock under the hood, you can clean columns in bulk or specify custom instructions. You can even execute post-cleaning transforms using simple prompts, allowing you to split names, calculate averages, merge columns, or extract substring values without writing a single line of Python or Javascript code.
