Meeting Districts Where They Are: Faster, Easier CSV Mapping with Cuelang

Delivering a Smarter, Faster Way to Work with Rostering Logic

The latest update to Ednition’s Cuelang Editor brings powerful usability enhancements to help EdTech companies streamline rostering. Just in time for back-to-school season!

Working with district data can mean handling arbitrary CSVs, complex transformations, and granular filtering needs. It’s rarely straightforward. That’s where Cuelang becomes your most powerful tool.

Cuelang is the language RosterStream uses for mapping, filtering and validating data, allowing EdTech companies to meet districts where they are and transform CSVs into clean, OneRoster-compliant data.

Our latest visibility and usability enhancements make working with data simpler and more efficient. The redesigned split-screen interface streamlines editing with automatic in-line validation, real-time OneRoster spec checks, and improved AI-generated Cuelang accuracy work together to reduce implementation time and support needs.  

These enhancements are driven by user feedback and our ongoing commitment to making onboarding as seamless as possible. When our customers move faster, districts benefit too, with cleaner data, faster onboarding, and fewer support issues.

Key Feature Enhancements

Expanded Split-Screen Full View

Edit on the left, see results on the right in a full-screen layout that gives you more space to work with complex logic.

Real-Time Auto-Validation

No more clicking the “validate” button after every change. The Editor now validates Cuelang as you type, catching syntax or structural errors immediately.

Built-in OneRoster Validation

Your logic is now checked against the OneRoster specification in real-time.
Augmentation note: SourcedId is all that's required for augmentation mapping (Alt ID also supported).

RosterAI Improvements

We’ve enhanced the RosterAI “Generate Cuelang” feature with better fallback and retry logic if the initial generation doesn’t pass validation. This leads to fewer errors, faster edits, and a smoother path to production.

Why It Matters

District data rarely comes clean or consistent. CSVs arrive in arbitrary formats, and with inconsitencies in headers, IDs often need to be remapped, and filtering out unnecessary data often eats up valuable engineering time. That’s why these updates are designed to reduce implementation friction so that your EdTech application can get connected to districts as quickly as possible.

We’re always evolving our tools to help our customers deliver the best possible experience to their district partners. This latest update is a reflection of that, taking your feedback and turning it into real, meaningful improvements.
