Flatfile

Flatfile provides a data exchange platform that helps businesses import, clean, and transform messy spreadsheet and file data into structured formats their systems can use. It targets software companies and enterprises that need to onboard customer data during implementation, particularly B2B SaaS products requiring CSV or Excel uploads from clients. The platform embeds directly into web applications, giving end users a guided interface to map columns, validate fields, and correct errors before data enters the destination system. Developers use Flatfile's APIs and SDKs to customize validation rules, transformation logic, and workflows tailored to their specific data schemas. Its core value lies in reducing the engineering effort typically spent building custom import tools while improving data quality and accelerating customer onboarding timelines.
