Top Flatfile Competitors in 2025

Flatfile is a data onboarding solution offering an embedded CSV importer, allowing users to seamlessly upload and import data into their system. Flatfile enables users to perform data transformations to align their data with the system’s schema and map CSV data from external systems into yours. Despite the promising features of Flatfile for data management and import processes, it has certain shortcomings. First and foremost, Flatfile is prohibitively expensive for many companies looking for a solution for data imports. Additionally, because Flatfile stores customer data on its system, certain companies are uncomfortable with its solution.

Let’s look at the top five Flatfile competitors in the market.

Flatirons Fuse

Flatiron Fuse is an AI-powered CSV import tool that is a powerful Flatfile alternative. Customers of Fuse can embed a CSV importer directly into their website, allowing users to upload CSV or spreadsheet data from any external source and quickly transform the data to match the target system.

Flatirons Fuse’s artificial intelligence capabilities enable users to map data from external systems to the target system efficiently. It has tools to allow users to address validation errors, ensuring that data imported into a system is clean and matches the system’s needs.

Flatiron’s Fuse can be seamlessly embedded into your website or application for use by internal teams or customers alike. Internal teams can use this tool to facilitate the import of customer data from new sales or by customers themselves to upload their data to your system. Flatirons Fuse is an alternative to CSVBox.

With Flatiron Fuse, organizations can deliver a streamlined customer data onboarding experience while freeing developer time with just a few lines of code. One of the key selling points of Flatiron Fuse is its ability to provide the most straightforward method for importing client data from any source. Some of the key features of Flatirons Fuse include:

• Embeddable CSV import tool

React CSV Importer

If you are looking for a bare-bones open-source library for CSV imports, React CSV importer can be a practical Flatfile competitor to look at. While React CSV Importer is more development work than an off-the-shelf tool like Flatfile or Flatirons Fuse, some companies may prefer to build their own import experiences.

Features include:

• Raw file preview
• Drag-drop UI to remap input columns as needed.
• i18n (EN, DA, DE, IT, PT, TR or custom)
• Standalone CSS stylesheet (no frameworks required)
• TypeScript support
