BEYOND A FEATURE LIST

A service shaped around the outcome.

Every engagement is scoped around one valuable operating result, the people responsible for it and the evidence that will prove improvement.

01 · THE CHALLENGE

Understand what creates the risk.

A business-critical spreadsheet is rarely just a file. It contains formulas, status conventions and operating knowledge, while approvals happen in email and employees maintain their own copies. As more people depend on it, the company loses control over versions, access, changes and reporting. The development problem is not converting cells into screens. It is discovering the full workflow around the workbook without losing the rules the business already trusts.

02 · THE SOLUTION

Design the complete working system.

Myriah audits the workbook, linked files, formulas, macros, users and manual handoffs before designing the application. The first release creates one shared source of truth with structured records, validation, role-based queues, approvals, audit history and dependable reports. Existing calculations are tested against representative examples. Integrations are limited to the systems the workflow genuinely needs, keeping the first release focused and easier for employees to adopt.

03 · LAUNCH AND OWNERSHIP

Deliver safely and leave you in control.

Migration begins with a clean representative data set and a reconciliation plan. Users test ordinary work, exceptions and reports before production. The original workbook can remain available as a read-only archive during acceptance, with clear ownership of corrections and a rollback path. After launch, the team measures time spent preparing reports, error frequency, approval delay and adoption. Further spreadsheets are replaced only after the first workflow has earned operational trust.

BUYER QUESTIONS

What to know before requesting a proposal.

Can you convert our Excel spreadsheet into a web application?

Yes, when the spreadsheet controls a repeatable business workflow. We first document formulas, users, approvals, exceptions and reports, then design a controlled application around the process.

Will we lose our spreadsheet data?

No. Migration is rehearsed with a representative data set, totals are reconciled and original files can remain as read-only archives during acceptance.

How much does Excel to web app development cost?

A focused first release starts from €3,500. Complex macros, historical cleanup, several integrations or advanced reporting increase the scope.
