The position
Spreadsheets, engineered.
VZU Sheets is the spreadsheet-as-API practice. The spreadsheet is the most-used data tool in the world. The spreadsheet is also the most-misused data tool in the world. VZU Sheets treats the spreadsheet like a database: type-checked, validated, queryable, auditable.
We do spreadsheet engineering. We do spreadsheet validation. We do spreadsheet-as-API. We do spreadsheet-to-database migrations. The output is a spreadsheet that doesn't break, a validation report, a queryable API, or a migration path. The work is the spreadsheet. The work is the data. The work is auditable.
VZU Sheets engineers are senior. They have shipped spreadsheets at scale. They know the formula patterns. They know the data patterns. They know when the spreadsheet is the right tool and when it's the wrong tool. They know that the right answer to "should we use a spreadsheet?" is sometimes "yes" and sometimes "no." The data is the work. The data is auditable.
The practice, in pictures
Three things we get right, every time.
Production The proof
BookFlow financial reconciliation. XLSX-based reconciliation.
XLSX-based financial reconciliation for the BookFlow platform, including the booking ledger, the Stripe payouts, the refund queue, and the tax export. Built by VZU Sheets in 3 weeks.
- → Type-checked headers with validation rules
- → Reconciliation against the booking ledger + Stripe payouts
- → Refund queue with status tracking
- → Tax export with jurisdiction-aware rules

The engagement
How we work, end to end.
- Format
-
XLSX + CSV
XLSX for the engineer. CSV for the operator. Both. The format is the contract.
- Validation
-
Type-checked headers
Every column has a type. Every type has a validator. The validator runs on save.
- API
-
Queryable
The spreadsheet is a database. You can query it. The query returns JSON. The query is auditable.
- Versioning
-
Git-tracked
Every change is a commit. Every commit has a diff. Every diff has a review.
- Migration
-
To Postgres when ready
When the data outgrows the spreadsheet, we migrate it. The migration is auditable.
The VZU Sheets practice
The work, in motion.
Every brief becomes a working product in days. Every product is engineered for the long term — clean architecture, real audit trails, real operators in the loop. The VZU Sheets practice at VZU is built on senior engineering, the NetWit runtime, and a refusal to ship anything we wouldn't put on a public domain.
