Turn your data template intoa collaborative workbook
You already have data templates you're using with your customers (whether or not they follow them). Instead of wasting time translating these business requirements into technical specifications, simply upload your templates to Flatfile. AutoBuild analyzes your documents like an experienced analyst would, understanding your needs and automatically creating a custom onboarding application for you.
AutoBuild’s capabilities aren’t limited to initial setup. If you need to make changes in the future, adding and modifying fields is just as simple. Preview changes in real time to ensure that what you intended is what you get.
Validation as easyas conversation
Build Mode offers flexibility for how you set validation rules for your data, with options for natural language or JavaScript and handy toggles for basic constraints. Move freely between these approaches based on what’s most efficient for the task at hand.
Toggle to setcommon rules
Even basic rules like making sure a field is unique or required would typically require a developer’s time to write code enforcing these constraints. But with Build Mode, these rules can be toggled on and off.
Use natural languageto create constraints
For more complex validation rules, type a natural language command and AI will interpret the goal, then generate the necessary code to automatically apply those rules to your workbook.
Write code forcomplete control
Easily switch to a code view to create your own validation rules for fields in JavaScript. You can also view or modify the code for any rules generated by toggle or natural language.

Sample records shapedby your requirements
Testing your configuration is an important step in ensuring it’s ready for customer data, but generating high-quality dummy data is time consuming and labor intensive.
As AutoBuild creates your schema and validation rules, it also produces relevant sample data with both valid and invalid records to help you test what you’ve built. Preview data is shown side by side with your validation rules and setup. As you make changes, you can immediately see how it will affect imported data.
Before you finish building, you’ll be confident that what you’ve configured will do exactly what you need it to do.
Chart the courseto clean data
Set users up for success from the start. Clear guidance means fewer errors and cleaner data. Build Mode lets you create an intuitive experience that keeps everyone on the right track, whether they're frequent users or first-time importers.
Guides
Guides allow you to leave helpful tips and instructions exactly where they’re needed, ensuring your team and customers always know what to do next. From field descriptions to custom messages, every part of your workspace can guide users toward successful data submission.
Guardrails
Guardrails keep your data quality high by preventing common mistakes. List requirements for validation, field completion, or any other criteria, and Guardrails will remind users to check each prior to submission.
Make itunmistakably yours
If you have customers importing to your workspace, you’ll want them to see your branding front and center. Customize your theme to reinforce your brand throughout your customer onboarding process.
Import directly from your website
Provide a URL and Flatfile will pull the logo and colors from the website and apply to your workspace.
Customize with code
For more extensive customization, you can use JavaScript and CSS. Flatfile supports modifying most UI elements, including colors, fonts, borders, and padding.
