Unlock the Power of Automation: Converting Excel to HTML Tables and Handling Null Values

Are you tired of manually converting Excel spreadsheets to HTML tables? Do you struggle with null values ruining your perfectly formatted tables? Look no further! In this comprehensive guide, we’ll show you how to harness the power of automation using Power Automate (formerly Microsoft Flow) to convert Excel to HTML tables and elegantly handle null values.

Why Automate Excel to HTML Conversion?

Manually converting Excel spreadsheets to HTML tables can be a tedious and time-consuming task, especially when dealing with large datasets. By automating this process, you can:

• Save time and effort
• Reduce the risk of human error
• Increase productivity and efficiency
• Focus on more strategic tasks

Getting Started with Power Automate

Before we dive into the automation process, make sure you have a Power Automate account and a basic understanding of its interface. If you’re new to Power Automate, start with their getting started guide.

Step 1: Connect to Your Excel File

In Power Automate, create a new flow and add an “Excel Online” trigger. Select “List rows present in a table” and connect to your Excel file.

  
    {
      "inputs": {
        "host": {
          "connection": {
            "name": "@{outputs('ExcelOnline')?.connectionName}"
          }
        },
        "method": "get",
        "uri": "/Tables/@{body('ExcelOnline')?.tableName}/rows",
        "body": "{}",
        "authentication": "@{outputs('ExcelOnline')?.authentication}"
      }
    }
  

Note: Replace `@{outputs(‘ExcelOnline’)?.tableName}` with the actual name of your Excel table.

Step 2: Convert Excel Data to HTML Table

Add a “Create HTML table” action and configure it to use the Excel data from the previous step.

  
    {
      "inputs": {
        "table": {
          "rows": "@{body('List_rows_present_in_a_table')?.value}",
          "headers": "@{outputs('Create_HTML_table')?.headers}"
        }
      }
    }
  

In the “Create HTML table” settings, specify the desired HTML table structure, including the column headers and formatting options.

Column Header	Column Type	Format
Column 1	String	Plain Text
Column 2	Number	Currency

Handling Null Values

When dealing with null values, you have several options to handle them elegantly:

Option 1: Replace Null with a Default Value

Use the “Replace” function to substitute null values with a default value, such as an empty string or a custom message.

  
    {
      "inputs": {
        "text": "@{body('List_rows_present_in_a_table')?.value}",
        "oldValue": null,
        "newValue": ""
      }
    }
  

Option 2: Omit Null Values from the HTML Table

Use the “Filter array” action to remove null values from the Excel data before creating the HTML table.

  
    {
      "inputs": {
        "from": "@{body('List_rows_present_in_a_table')?.value}",
        "where": "@not(equals(item()['Column 1'], null))"
      }
    }
  

Note: Replace `Column 1` with the actual column name you want to check for null values.

Step 3: Send the HTML Table via Email or Store it in a File

Finally, add an action to send the generated HTML table via email or store it in a file. You can use Power Automate’s built-in “Send an email” or “Create file” actions.

  
    {
      "inputs": {
        "body": "@{body('Create_HTML_table')?.html}",
        "subject": "Automated Excel to HTML Report",
        "to": "[email protected]"
      }
    }
  

Tips and Variations

To take your automation to the next level, consider the following tips and variations:

1. Use conditional logic to handle different scenarios based on the Excel data.

2. Add more advanced formatting options, such as conditional formatting or custom CSS.

3. Integrate with other Power Automate actions, such as sending notifications or updating a SharePoint list.

4. Use Power Automate’s scheduling feature to automate the process at regular intervals.
