Step 1: Clean Up Your Spreadsheet

Before we start building our web app, it is important that our Excel spreadsheet stores data in the correct format.

To do so, make sure that your spreadsheet's first row contains descriptive names of the data stored in each column.

For example, let's say your spreadsheet contains information on Products, Prices, and Quantities. Here's what your Excel spreadsheet should look like:

Product	Price	Quantity
Product 1	4.99	100
Product 2	5.99	4
Product 3	100.99	58

Unfortunately, the real world is rarely as well-structured as this spreadsheet. So here are a few points to note:

1. Make sure that your header row (row 1) only contains descriptive names for what is stored in each column. In our case, our header row contains Product, Price, and Quantity. Pick descriptive names for your columns and avoid adding unnecessary additional content to them.

2. Do not repeat information in multiple columns. For example, it is not advisable to have one column for "Products (non-perishable)" and another column for "Products (perishable)". Instead, have one column for "Product", and another column that classifies them as "Perishable" or "Non-Perishable".

3. Make sure that each cell only contains one piece of data. For example, in our case, it might be tempting to add discount information to our pricing, such as "5.99 (discounted to 4.99)". Don't.
If you do so, this data point is no longer usable in a calculation. Always make sure that every column only has one type of data such as text, numbers, options, or currencies.

4. Even if you have multiple values of the same item, do not put all of them into the same cell. For example, sometimes we might have more than one email address for a customer. How should we deal with this scenario in our spreadsheet?
The correct way to set this up is to have multiple "Email" columns, such as "Primary Email", "Secondary Email", or "Work Email" and "Personal Email". Do not store multiple emails in one cell.

Expert Tip: Useful Excel Commands For Cleaning Up Your Spreadsheet

To go from Excel to web app without too much trouble, it is advisable to spend some time looking at your existing data and make sure it's clean. As the saying goes: a stitch in time saves nine!

Here are our three favorite Excel functions for clean data:

TRIM: Excel's TRIM function deletes all leading, trailing, and in-between spaces except for a single space character between words. This works great for misspelled names.
Say some of your customers have misspelled their names when signing up on your website, such as "JohnDoe", or "Jane Doe □□□". The trim function will convert these two entries to "John Doe" and "Jane Doe".

CLEAN: The CLEAN function removes all nonprintable characters from text. This is useful if your database contains names with special characters that didn't get pasted correctly into your Excel, or if you have line breaks in your cell.

PROPER: The PROPER function converts the first character to upper case and all other characters into lower case.
For example, the function will convert "JOHn DoE" into "John Doe".

Later in this article, we will introduce you to a few helpful features that will make it easier for you to collect clean data in your web app.

Does your Excel spreadsheet fulfill the criteria above?

Your header row (row 1) only contains descriptive column names.
Every column contains unique information related to the column header.
Every cell in the same column contains only one piece of data of the same data type, such as a piece of text, numbers, etc.
Multiple data points of the same category are split across multiple columns.
Your data has been cleaned up using some of Excel's built-in functions.

If so, it's time to move to Step 2 to convert your Excel to a web app: setting up your database.

Step 2: Setting Up Your Database and Importing Data

Thanks to the work we just did in Step 1, going from Excel to a web app will be a lot easier now that we're starting with Step 2: setting up your database.

Having a database as your application backend is a critical step in converting Excel spreadsheets to web apps. We recommend MySQL, the world's most popular open-source database.

To create our database, we will use Five, which has a handy and easy-to-use visual database designer. Using Five's database designer, we can create a database table entirely in point-and-click. Make sure to have Five installed and running on your computer to follow along.

1. Create a New Application in Five

After installing Five, launch it on your computer. You'll be greeted by a screen that looks like this:

Click on Applications near the top left corner of the screen, and right below the hamburger menu icon.
Now, click on the yellow Plus icon. A new window "New Applications Record" will appear.
Give your application a Title, such as "My First App".
Save by clicking the Tick Mark in the top right corner.

Here's what your screen should now look like. If "My First App" is your first application, you will not see any other applications in the list on left:

2. Create Your Database and Import Data

It's time to build your database and import your data. To start click the blue Manage button on the top right of the screen near the Five logo.

Now click on Data and then Tables to land on the screen shown below. Looks pretty empty doesn't it?

Let's go ahead and create a database table. Click on the Lightning icon (do not click the yellow plus icon) to launch Five's Table Wizard which looks like this:

Give your table a Name. Let's go with Inventory.
Now click on the Plus icon on the right side of the screen. Click three times to create three database fields for Product (data type: text), Price (data type: float; display type: float.2), and Quantity (data and display type: integer). Below is what your table should look like. Save by clicking the Tick mark.

Now let's import our data from our Excel spreadsheet. Find and click the Import CSV into Table icon to get started:

To import your data make sure it is stored in a CSV file. If you'd like to use the data provided above, download our CSV file here.

Five's Import Data lets you select the database table you'd like to import data into. In our case, there is only one table: our inventory table. So go ahead and select it from the dropdown box.
Next, click on Choose File and find the Inventory.csv file. Upload it.
Five will automatically map the fields of your CSV file to your database fields, provided you have been following this tutorial and your database fields have the same name as the top row of your CSV file.
For InventoryKey select Generated.
Click on the Tick mark to upload your data.

Congratulations! You have created a database table in a MySQL database and have populated it with data! In the third and last step, we will add a form to our application and launch and preview it.

Step 3: Adding a Form and Previewing Your Application

We have already created our application backend: a relational database with a single table that stores information about our products, prices, and quantities. But a database is not a web app. So let's move on to step 3 of converting our Excel to a web app.

1. Adding a Form

Five makes it really easy to build a form for your end-users. To get started, click on Visual and then on Forms.

Click on the Lightning icon (do not click the yellow plus icon) to launch Five's Form Wizard.
There's only one thing you need to do in the form wizard. Select Inventory as your Main Table.
Save by clicking the Tick mark.

It is time to preview our application!

2. Preview Your Application

Click on the Run icon at the top right corner. This will launch your application in a new window.

Here's what your application will look like:

Excel to Web App: Next Steps

Well done! You have successfully built and deployed your first web application in Five. Instead of managing your data in an Excel spreadsheet, you can now use a modern web application to store, retrieve, and process your data. And it took only three steps to go from Excel to web app!

Five's prebuilt user interface has automatically created an Inventories menu item for you. You can also see your Products in the list to the left of the screen. Last, by selecting one of the products, you can see its details, and make changes to them as necessary. Five also comes with a pre-built search and filtering feature.

What else can you develop in Five? Plenty of things! Check out this screenshot of a finished application to get a sense of what's possible:

You can theme it to make it look more professional. Here's our guide to creating and attaching a theme to your application.
You can add charts or dashboards to your application.
You can show your data in an editable grid by following our Northwinds tutorial.
Remember how at the top we spoke about capturing clean data? Why not add a few data validation rules to your application?
You can add a login and terms & conditions consent screen to your application, and give users different roles and permissions.

In short, we have barely scratched the surface of what's possible in Five! For further inspiration on what can be built in Five, visit our Use Cases.

Happy coding!
