Convert MS Access and Excel to a Web Application

Last updated: October 9, 2026

Short answer: If your company runs on a single Access database or a handful of Excel files and you are now hitting file locks with multiple users, corrupt and inconsistent data, no remote or mobile access, and limited reporting, it is time to turn it into a real web application. The Barsavosh Fanavaran team converts your Access database and Excel workbooks, together with all their data, forms and business logic, into a fast, secure, multi-user web platform (more than 50 concurrent users).

On this page we explain why Access and Excel fall short for growing businesses, exactly what moving to the web solves, and how the migration process works. For an overview of our software rewrite and modernization service, see the Rewrite and Convert Legacy Software to Web page.

Signs that Access or Excel no longer meets your needs

File locking with multiple users: When more than a few people open the file at the same time, Access slows down, locks, or the file becomes corrupt.
Data corruption and inconsistency: Access and Excel files corrupt easily, and different copies of the same file produce conflicting figures.
No remote or mobile access: Staff can only work at that one computer or on the internal network; not from home, and not from a phone.
Weak security and access control: Defining which user can reach which part is very limited in Access and Excel.
Volume and performance limits: As data grows, Access reaches its size and speed ceiling and heavy reports slow to a crawl.
Manual backups: The lack of an automatic, secure backup copy raises the risk of losing your data.

What converting Access and Excel to the web solves

True multi-user support: Dozens of users work at the same time with no file locking (more than 50 concurrent users).
Access from anywhere: From a browser, at home, at another office, or on a phone, with no software to install.
A single, secure source of data: An end to dozens of scattered files; all data in one secure database with automatic backups.
Precise access control: Define a role and access level for every user.
Live reports and dashboards: Instant reports that used to take hours in Excel are ready with a single click.

How we convert Access software to a web application

Review and analysis: We examine your Access tables, queries, forms and macros (or your Excel sheets and formulas) to fully understand the business logic.
Web architecture design: We redesign the data structure into a professional, scalable database.
Secure data migration: Every existing record in Access and Excel is transferred to the new platform securely and completely; no data is lost.
Rebuilding forms and reports: The forms, searches and reports you already know are rebuilt in a modern, user-friendly interface.
Testing and deployment: After thorough testing, the platform goes live, and we take on ongoing support and future updates.

Access and Excel versus a web application

Feature	Access / Excel	Web application
Concurrent users	Limited, with locking	More than 50 users
Remote and mobile access	None	From any browser and device
Security and access control	Weak	Role-based and precise
Corruption and backups	High risk, manual	Secure database, automatic backups
Reporting	Slow and manual	Live dashboard

Cost and timeline of the conversion

Cost and time depend on the number of Access tables and forms, the volume of data to be migrated, and any new features you want. Small projects usually take a few weeks and larger platforms a few months, and in many cases the conversion can be done stage by stage so the cost is spread out and work never stops. Simply send us your Access/Excel file or a description of your current process to receive a free cost and timeline estimate.

Which businesses benefit most

Companies that manage their accounting, inventory, sales, human resources or internal processes with Access and Excel. For example, many warehouses run on Excel and are replaced by the Avadar inventory management software, while factories with several separate production, purchasing and financial files bring everything together in one centralized system with the integrated Data ERP platform for manufacturers.

Frequently asked questions

Will all of our Access and Excel data be migrated?

Yes. Every record, table and piece of existing information is transferred securely and completely to the web version’s database, so your work history is fully preserved.

Does the new software support many concurrent users?

Unlike Access, which locks with multiple users, the web version is designed for dozens of concurrent users (more than 50 users).

Will our Excel formulas and calculations be preserved?

Yes. Your calculation logic and formulas are reviewed and rebuilt in the new platform so the outputs match your expectations exactly, and run even faster and more accurately.

How much does converting Access to the web cost?

The cost depends on the size and complexity of your current file, the number of forms and reports, and any new features. After reviewing your file we provide a clear, free estimate.

How long does the conversion take?

Depending on the size of the project, from a few weeks to a few months; with staged delivery you receive the key parts sooner.
