Question details

The user needs to fix an Excel data validation drop-down list that stops working or shows blank entries because allowed values were entered directly in the validation dialog and contain consecutive commas.

Product: WPS Office Spreadsheets
Device & OS: not provided
Scenario: The user is managing a workbook with an Excel data validation drop-down list that stops working or behaves inconsistently.
Observed behavior: The drop-down list contains blank entries or behaves inconsistently because the values were typed directly in the validation dialog with consecutive commas.

Before you start

Open the workbook in WPS Office Spreadsheets and identify the cell or range where the data validation drop-down list is applied. Have the list of allowed values ready in a separate worksheet or Excel Table before changing the validation source.

Solution 1Recommended

Store the Validation List in a Worksheet Range or Excel Table

Use this solution for a stable, easy-to-maintain drop-down list when the current list is long, contains blank entries, or was typed directly as comma-separated values.

Entering a long comma-separated list directly in the Data Validation dialog can create blank entries from consecutive commas and may behave differently across Excel installations. Storing the allowed values in a worksheet range or Excel Table makes the list visible, easier to maintain, and less error-prone.

Create a dedicated list sheet

Open your workbook in WPS Office Spreadsheets and add a new worksheet. Type each allowed value in its own cell in a single column, leaving no blank rows unless you intentionally want a blank entry.

Convert the list to an Excel Table

Select the list cells, go to the Insert tab, and choose Table. In the Create Table dialog, check My table has headers if applicable, then click OK.

Select the validation target cells

Click the cell or range where the drop-down list should appear, go to the Data tab, and choose Data Validation.

Set the source to the table range

In the Data Validation dialog, set Allow to List. In the Source box, select the table column or enter a named range that refers to the list, then click OK.

Protect the list sheet if needed

Right-click the list sheet tab, and choose Hide or Protect Sheet so users do not accidentally edit or delete the allowed values.

Drop-down list corrected: The drop-down list now reads from a stable worksheet range or Excel Table and no longer creates blank entries from stray commas.

Solution 2

Use a Named Range for Reusable Validation Lists

Use this solution when you want a shorter source reference in the Data Validation dialog or need to reuse the same list across multiple sheets.

Fix an Excel Data Validation Drop-Down List with WPS Office Spreadsheets

WPS Office Spreadsheets can fix the drop-down list by storing allowed values in a dedicated worksheet range or Excel Table and pointing Data Validation to that source, avoiding blank entries from consecutive commas.

2. Create a dedicated list range: Add a new sheet, enter each allowed value in its own cell, and remove blank cells unless they are intentional.
3. Apply Data Validation from a range: Select the target cells, click the Data tab > Data Validation, set Allow to List, and select the new list range as the Source.
4. Test the drop-down list: Click a validated cell and open the drop-down arrow to confirm the list shows only intended entries.

Frequently Asked Questions

Why does my drop-down list show blank options when I typed a comma-separated list?

Consecutive commas in the Source box create empty list entries. Move the values to a worksheet range or Excel Table and select that range as the validation source to remove unintended blanks.

Can I use an Excel Table as a validation source in WPS Office Spreadsheets?

Yes. Select the table column in the Source box of the Data Validation dialog, or define a named range that refers to the table column. The list updates as you add or remove rows.

How do I hide the list sheet but keep the drop-down working?

Right-click the sheet tab and choose Hide or Protect Sheet. Data Validation continues to read hidden sheets, and using a named range can help maintain compatibility.

What should I do if the drop-down works in desktop Excel but not in Excel for the web?

Store the list in a worksheet range or named range instead of a direct comma-separated list, save as .xlsx, and test in WPS Office Spreadsheets and Excel for the web. Older builds may not support direct list strings consistently.

Can WPS Office open and repair an Excel file with a broken validation list?

Yes. Open the file in WPS Office Spreadsheets, open Data > Data Validation, change the Source to a clean cell range or table column, and save the workbook. Your .xlsx formatting remains intact.
