Never build a CSV importer again

Built for CSV import

Format CSV/XLS files on import without wrangling data on your backend.

Quick deployment

Flatfile Portal integrates without lengthy development cycles or technical debt.

Robust API component

Post the clean, structured JSON, to any endpoint using Flatfile Portal's API.


Intuitive CSV column-mapping

Flatfile Portal intelligently maps 95% of imported spreadsheet header columns using fuzzy-matching. Your users will confidently import their data, correctly, the first time, freeing you from having to manually clean spreadsheet data.


Integrate a CSV import feature in minutes, no maintenance

Set up a target data model with a few lines of JSON. The configuration snippet is integrated into your application and called through a JavaScript button. Most engineers integrate Flatfile Portal in a week.


Powerful Data Hooks™ 

Imported CSV data is typically unstructured, and full of validation errors. Portal intelligently formats incoming spreadsheet data without the need to use CSV/Excel templates, or wasting time fixing data on your backend.

Flatfile is data privacy

Client and on-premise options

GDPR compliant

Flatfile is SOC2, and HIPAA compliant enabling sensitive and personal identifiable information (PII) data to be safely transmitted during import.

Portal uses AWS S3 buckets for data storage and encryption, while providing alternate deployments options for sensitive data handling environments.

Flatfile can execute a data processor agreement with your company to ensure personal data is never compromised when using Portal.

About Flatfile

Flatfile started out of our own frustration with importing data into SaaS products. Across a decade of experience in enterprise software, we’ve built too many bespoke import scripts, spreadsheet templates, and software tools, all trying to solve the same core problem.

Flatfile provides two business products, Portal and Concierge, which solve data onboarding inefficiencies.
