How to Replace Excel with a Web Application and Custom Apps

Replacing Excel with a web application is often the first step businesses take when spreadsheets start slowing them down. But the real transformation happens when you go one step further and replace spreadsheet workflows with custom apps designed around how your business actually works.

In this guide, you’ll learn how to replace Excel with a web application, how to turn spreadsheet workflows into custom apps, and how Noloco helps you do this without rebuilding your systems from scratch.In this guide, you’ll learn how to replace Excel with a web application, how to convert spreadsheet to web application, how to turn spreadsheet workflows into custom apps, and how Noloco helps you do this without rebuilding your systems from scratch.

Why Businesses Move Beyond Excel and Spreadsheet Workflows

Excel and spreadsheets are flexible, but flexibility comes at a cost.

As spreadsheets evolve into operational tools, teams run into problems like:

• Manual data entry and hidden errors
• Multiple versions of the same file
• No real user permissions or accountability
• Slow performance as data grows
• Complex workflows managed manually

At this stage, the issue isn’t Excel itself—it’s that spreadsheets were never designed to run business workflows.

That’s why many teams choose to replace Excel with a web application and eventually replace spreadsheet workflows with custom apps built for their processes.

While Excel is great for analysis, it wasn’t designed to run business processes. The table below highlights when it makes sense to replace Excel with a web application.

This is why many teams choose to convert spreadsheet workflows into custom apps once Excel becomes operational.

What It Means to Replace Spreadsheet Workflows with Custom Apps

Replacing spreadsheet workflows doesn’t mean abandoning your data.

It means:

• Turning spreadsheets into structured databases
• Replacing rows and columns with forms, dashboards, and workflows
• Giving users clear interfaces instead of raw data
• Automating steps that were previously manual

A custom app becomes the system your team actually uses, while spreadsheets fade into the background.

Noloco is designed specifically to help businesses make this transition.

Step 1: Choose a Spreadsheet Workflow to Replace

Start with one workflow, not everything at once.

Good candidates include spreadsheets used for:

• CRM or customer tracking
• Operations and internal processes
• Project or task management
• Inventory or asset tracking
• Reporting and approvals

If a spreadsheet is:

• Used daily
• Shared across teams
• Central to decision-making

…it’s a strong candidate to replace with a web application.

Step 2: Import Your Spreadsheet Data into Noloco

Noloco lets you import data directly from:

• Excel files
• Google Sheets
• Airtable
• SQL

You can easily import CSV or, even connect directly external data, like Airtable, and keep this is sync automatically.

Once imported, your spreadsheet becomes a relational database, not a file that gets copied and emailed.
Data are organized into tables, tables are linked between them, and you can use typed fields, calculation, formulas, and more.
What happened is that being a database, the relations between data never break, and everything is updated in real-time.

This immediately:

• Eliminates version control issues
• Creates a single source of truth
• Improves performance with larger datasets

You’re no longer “working in Excel”, you’re building on top of your data.

Step 3: Turn Raw Data into a Custom App Interface

One of the biggest shifts when you replace spreadsheet workflows with custom apps is how users interact with data.
When you import data for the first time, Noloco creates automatically that into an App, and then you totally free to edit and customize it as much as you need.

Instead of editing rows directly, Noloco lets you create:

• Clean list views
• Detail pages for individual records
• Custom layouts per role (admin, staff, client)

This makes your data easier to understand and much harder to break.

Step 4: Replace Manual Data Entry with Forms

Spreadsheets are fragile because anyone can edit anything.

Custom apps fix this with forms.

With Noloco, you can create:

• Internal forms for your team
• Client-facing forms or portals
• Mobile-friendly data entry

Forms enforce:

• Required fields
• Valid data types
• Controlled inputs

This dramatically reduces errors and is one of the main reasons businesses replace Excel with a web application.

Step 5: Add Rules and Permissions to Your Workflow

In Excel, access control is limited. Once someone has the file, mistakes are easy.

With Noloco, you can:

• Control who can view, edit, or delete data
• Show different data to different roles
• Protect sensitive information

Noloco offer very granular access control, that let you can even control at single record of the databse.

This turns spreadsheet workflows into structured, secure processes, not open-ended files.

Step 6: Build Real-Time Dashboards Instead of Reports

Spreadsheet reports are static and time-consuming to maintain.

Custom apps use live data.

With Noloco dashboards, you can:

• Track KPIs in real time
• Filter by user, status, or date
• Share dashboards securely

Reports update automatically as data changes, no manual refresh required.

Step 7: Automate Spreadsheet Workflows

This is where replacing spreadsheet workflows with custom apps delivers the biggest gains.

With Noloco automations, you can:

• Trigger actions when data changes
• Send notifications or emails
• Update records automatically
• Generate documents or invoices

Instead of managing processes manually in Excel, your app handles them for you.

Step 8: Integrate Your Custom App with Other Tools

Excel sits in isolation.

Web applications connect systems.

Noloco can integrate with:

• CRMs
• Accounting tools
• Payment providers
• Internal databases
• External APIs

This turns disconnected spreadsheet workflows into end-to-end systems.

Steps recap

The table below summarizes how businesses typically move from Excel to a web application by replacing spreadsheet workflows with custom apps.

Together, these steps show how teams can replace Excel with a web application without rebuilding their systems from scratch.

Example: Replacing an Agency “Master Spreadsheet” with a Custom App

Many agencies and professional services teams rely on a single “master spreadsheet” to run their business.

This file often includes:

• Client details and contacts
• Project status and timelines
• Assigned team members
• Budgets, invoices, and payment status
• Notes, updates, and internal comments

Over time, this spreadsheet becomes business-critical, and increasingly fragile.

What this looks like in Excel

• Multiple tabs for clients, projects, and tasks
• Manual updates and copy-pasting between sheets
• Clients accidentally seeing internal notes
• Team members overwriting data or working on outdated versions
• Reporting done manually at the end of each week or month

What this looks like as a Noloco custom app

When you convert this spreadsheet into a web application with Noloco:

• Clients, projects, and tasks become structured records, not rows
• Your team uses forms to update project status instead of editing cells
• Clients access a secure portal to view only their own projects
• Internal notes stay internal, protected by permissions
• Project dashboards update automatically in real time

The same data still exists, but the workflow is no longer dependent on a shared file.

Example: Managing Customer Data and Interactions Beyond Excel

Another common spreadsheet workflow businesses replace is customer tracking.

In Excel, this often includes:

• A list of customers and contact details
• A column for “last contacted”
• Free-text notes for interactions
• Manual reminders and follow-ups

As usage grows, problems appear:

• No history of interactions per customer
• No accountability for follow-ups
• Data inconsistencies across versions

By replacing this spreadsheet with a custom app:

• Each customer gets a dedicated record
• Interactions are logged through structured forms
• Follow-ups can trigger reminders or automations
• Managers get real-time visibility without asking for updates

This is a common first step for teams looking to replace Excel with a web application while keeping their existing data.

When Should You Replace Excel with a Web Application?

Excel is still useful for:

• One-off analysis
• Small, personal datasets
• Temporary calculations

But once a spreadsheet becomes:

• Shared
• Operational
• Business-critical

…it’s time to replace Excel with a web application and start replacing spreadsheet workflows with custom apps.
