6. Choice
7. Lookup
8. Yes/No
9. Person or Group

Practical Transformations

Single Line of Text to Choice

To ensure data consistency, convert a "Single Line of Text" column to a "Choice" column.

Steps

1. Navigate to List Settings:
   • Open your SharePoint list.
   • Click on the gear icon and select "List settings".
2. Create New Choice Column:
   • Under "Columns", click "Create column".
   • Name the new column appropriately.
   • Select "Choice" as the column type.
   • Define the choices and configure other settings like "Default Value".
3. Migrate Data:
   • Using a SharePoint list management tool (like Power Automate or a custom script), transfer the data from the old "Single Line of Text" column to the new "Choice" column.

Multiple Lines of Text to Single Line of Text

If the text length is manageable, converting "Multiple Lines of Text" to "Single Line of Text" can enhance search and sorting capabilities.

Steps

1. Navigate to List Settings:
   • Open your SharePoint list.
   • Click on the gear icon and select "List settings".
2. Create New Single Line of Text Column:
   • Under "Columns", click "Create column".
   • Name the new column.
   • Select "Single line of text" as the column type.
3. Migrate Data:
   • Use a SharePoint list management tool to transfer the data from the old column to the new "Single Line of Text" column.

Date and Time to Choice

If specific dates need predefined options, transform a "Date and Time" column to a "Choice" column.

Steps

1. Create New Choice Column:
   • Follow the similar steps to create a choice column as described above.
   • Define your date choices.
2. Migrate Data:
   • Transfer data using tools like Power Automate.

Choice to Lookup

For dynamic data consistency across lists, convert a "Choice" column to a "Lookup" column.

Steps

1. Create Lookup List:
   • Create a new list to hold the choices.
   • Populate it with the required items.
2. Create Lookup Column:
   • In the original list settings, create a new column.
   • Select "Lookup" as the column type.
   • Link it to the newly created list.
3. Migrate Data:
   • Transpose the data from the "Choice" column to the new "Lookup" column using SharePoint tools.

Yes/No to Choice

For granularity beyond a Boolean value, convert a "Yes/No" column to a "Choice" column.

Steps

1. Create New Choice Column:
   • Similar to steps described above.
   • Define choices (e.g., Yes, No, Maybe).
2. Migrate Data:
   • Use SharePoint list management tools for data migration.

Summary

By transforming column types appropriately in SharePoint, you enforce data consistency, facilitate better search and sorting, and enhance the overall usability of your lists. Use SharePoint's built-in tools and management scripts (such as Power Automate) for efficient data transformation and migration.

Practical Implementation: Converting Free-Form Columns to Drop-Down Menus in SharePoint

Step 1: Identify the Column to Convert

Start by identifying the free-form text column that you want to convert to a drop-down menu.

Step 2: Create a New Choice Column

1. Navigate to your SharePoint list.
2. Click on the settings gear in the top right corner and select "List settings."
3. Under the Columns section, click "Create column."
4. Set the column name (e.g., "New Choice Column").
5. Select the "Choice (menu to choose from)" option.
6. Enter the choices you would like to appear in the drop-down menu. Make sure to include all possible values from the original free-form column.
7. Click "OK" to create the column.

Step 3: Populate the New Choice Column

To ensure you do not lose any data from the original free-form column, you will need to copy its data to the newly created choice column.

Using SharePoint’s Quick Edit Feature

1. Go to your SharePoint list.
2. Click on "Quick Edit" from the command bar.
3. Copy the data from the old free-form column and paste it into the newly created choice column rows.
   • Ensure that the existing data fits the defined choices in the newly created column; otherwise, manual correction will be needed.

Using a Script (if Available)

In some cases, you might prefer to automate this process. SharePoint does not provide direct scripting within its UI, but you can use tools like PowerShell with SharePoint PnP (Patterns and Practices) or use Microsoft Flow (Power Automate) for better precision.

Example PowerShell Script Using SharePoint PnP

Before using this script, ensure you have the SharePoint PnP PowerShell module installed.

# Connect to SharePoint
Connect-PnPOnline -Url "https://yoursharepointsiteurl" -UseWebLogin

# Define variables
$sourceColumn = "OldFreeFormColumn"
$targetColumn = "NewChoiceColumn"
$listName = "YourListName"

# Get items from the list
$items = Get-PnPListItem -List $listName -PageSize 1000

foreach ($item in $items) {
    # Get the value from the source column
    $value = $item[$sourceColumn]

    if ($value -ne $null -and $value -ne "") {
        # Update the target column with the value
        Set-PnPListItem -List $listName -Identity $item.Id -Values @{$targetColumn = $value}
    }
}

# Disconnect
Disconnect-PnPOnline

Step 4: Validate Data and Clean Up

1. After populating the new column, compare the data in the original and new columns.
2. Manually check for any discrepancies or entries that did not fit the choice criteria and adjust them.
3. Validate the data to ensure consistency.

Step 5: Remove the Old Free-Form Column

Once data validation is complete and you are confident that the new choice column accurately reflects the data:

1. Go to "List settings."
2. Find the old free-form column under Columns.
3. Click on the old column name and select "Delete" from the column settings page.

By completing these steps, you've effectively enhanced the usability and data consistency of your SharePoint list by transforming a free-form text column into a structured drop-down menu.

Configuring Drop-Down Menu Options & Validation in SharePoint

In this part of the project, we will discuss a practical implementation for configuring drop-down menu options and validation in a SharePoint list. We'll use SharePoint's out-of-the-box functionality for this purpose.

Configuring Drop-Down Menu Options

1. Navigate to Your SharePoint List

   • Go to your SharePoint site.
   • Open the list where you want to configure the drop-down menu.

2. Modify an Existing Column or Create a New Column

   • Click on the settings gear icon in the upper right corner.
   • Select "List settings."
   • To create a new column, click on the "Create column" link.
   • To modify an existing column, select the column name under "Columns."

3. Set the Column Type

   • In the "Name and Type" section, set the column type to "Choice (menu to choose from)."

4. Configure Drop-Down Options

   • In the "Additional Column Settings" section, enter your choice options, each on a new line in the "Type each choice on a separate line" box.
   • Example:

     Option 1
     Option 2
     Option 3

5. Default Value and Display Options

   • If you want to set a default value, enter it in the "Default value" box.
   • Choose how you want to display the choices (drop-down menu, radio buttons, or checkboxes) by selecting the appropriate option.

6. Save Your Changes

   • Click "OK" to save your configuration.

Implementing Validation

1. Navigate to Column Settings

   • Go to your SharePoint list.
   • Open the settings gear icon and go to "List settings."
   • Select the column you want to apply validation to.

2. Configure Column Validation

   • Scroll down to the "Column Validation" section.
   • Enter your validation formula in the "Formula" box. For example, to ensure the user selects something from the drop-down menu:

     =IF(NOT(ISBLANK([Your Column Name])), TRUE, FALSE)

   • Enter a user message in the "User message" box that will be displayed if validation fails. For example:

     Please select an option from the drop-down.

3. Save Your Changes

   • Click "OK" to save the validation rules.

This practical implementation covers configuring drop-down menu options and setting up validation in SharePoint lists. It utilizes built-in functionalities without requiring additional custom code, ensuring that the list is user-friendly and data entry is consistent.

Testing and Verifying Column Changes in SharePoint Lists

1. Select an Existing List Item

   • Click on an existing item in the list to edit it.

2. Modify Columns

   • Change the values in the newly transformed columns.
   • Ensure drop-down options appear correctly and that any validation is triggered as expected.

3. Save Changes

   • Save the item and ensure that changes are preserved.
   • Check that no data corruption has occurred.

Step 4: Export and Review Data

Export the list to Excel to further validate the data types and consistency.

1. Export List

   • Navigate to the list.
   • Click on the "Export to Excel" button in the command bar.

2. Open in Excel

   • Open the downloaded Excel file.
   • Review the data to ensure that the transformed columns display the correct data.

Step 5: Automated Testing (Optional)

If you have scripting capabilities, you may automate some of the testing processes.

Script Example

In PowerShell using SharePoint PnP (Patterns and Practices) library:

# Connect to SharePoint
Connect-PnPOnline -Url "https://yourtenant.sharepoint.com/sites/yoursite" -Credentials (Get-Credential)

# Get List Items
$listItems = Get-PnPListItem -List "YourListName"

# Iterate through items and verify column values
foreach ($item in $listItems) {
    $columnValue = $item["YourColumnName"]
    if ($columnValue -notin @("ValidOption1", "ValidOption2", "ValidOption3")) {
        Write-Host "Validation failed for item ID: $($item.Id)"
    } else {
        Write-Host "Item ID: $($item.Id) passed validation"
    }
}

# Disconnect
Disconnect-PnPOnline

Note: Ensure that you have the necessary permissions and the PnP PowerShell module installed (Install-Module SharePointPnPPowerShellOnline).

Conclusion

Testing and verifying column changes are essential for maintaining data integrity and ensuring usability after transforming column types in SharePoint lists. Follow the steps carefully, and optionally implement automated tests to streamline the validation process.
