Pioneering the Data Import Revolution

Introducing TableFlow: The Open Source CSV Importer

In the year 2022, TableFlow emerged as a beacon of innovation, unveiling its groundbreaking solution to the world: an open source data import platform that revolutionizes the collection and transformation of customer data. With TableFlow at their disposal, businesses now have a powerful tool to simplify their data onboarding needs and streamline their operations.

Addressing the Problem

Why Companies Need TableFlow?

The need for TableFlow stems from the challenges that businesses often encounter while importing and sharing customer data. Traditional methods involve the use of spreadsheets and emails or integration with built-in systems. However, these approaches come with their fair share of downsides.
