Question details

The user needs to export dates to an XML file while maintaining a specific date format (like mm-dd-yyyy) instead of exporting as internal numerical values.

How to Preserve Excel Date Format When Exporting to XML

Product: Excel / WPS Spreadsheet
Device & OS: not provided
Scenario: Exporting spreadsheet data that has been mapped to an XML schema.
Observed behavior: Dates are exported to XML as internal serial numbers (e.g., 33747) instead of the visually displayed date format.

Before you start

Before exporting your data, verify the exact date format required by your target XML schema (such as YYYY-MM-DD or MM-DD-YYYY) to ensure proper mapping.

Solution 1Recommended

Use a Helper Column with the TEXT Function

The most reliable method to ensure dates export in a specific visual format is converting them to literal text strings using a formula.

Spreadsheet applications store dates internally as serial numbers. Changing the visual format of a cell only changes how it looks on your screen, not the underlying data that gets exported. Using the TEXT function forces the output to become actual text, which maps cleanly to XML.

Insert a helper column

Right-click the column letter next to your existing date column and select 'Insert' to create a new blank column.

Enter the TEXT formula

In the first cell of the new column, type =TEXT(A2,"mm-dd-yyyy") replacing A2 with your actual date cell reference and "mm-dd-yyyy" with your required format.

Apply formula to all rows

Click the small square at the bottom-right corner of the cell containing the formula and drag it down to fill the rest of your data rows.

Map the new column to XML

Open your XML Source task pane and drag the corresponding XML schema element onto this new helper column instead of the original date column.

Use a Helper Column with the TEXT Function

Flexible Formatting: You can customize the format string in the TEXT function. For example, use "yyyy-mm-dd" if your XML system requires the standard ISO 8601 date format.

Solution 2

Define the Field as a Date Type in the XML Schema

Modify your XML schema file (.xsd) to explicitly define the element as a date data type, allowing the export process to format it automatically.

Solution 3

Manually Enter Dates as Text

Format cells as text before entering data so the system treats the input as literal characters rather than convertible date values.

Frequently Asked Questions

Why does my exported date show up as a 5-digit number in XML?

Spreadsheet software stores dates internally as serial numbers representing the number of days elapsed since January 1, 1900. When exporting data without a specific text conversion or schema typing, the raw internal number is exported instead of the formatted visual display.

Can I fix the XML export by simply changing the cell format to 'Text'?

No. If you format a cell that already contains a date as Text, it will instantly convert the display to its internal serial number. You must either format a completely empty column as Text before typing the dates, or use the TEXT formula to convert existing dates.

What is the standard date format expected in most XML schemas?

The standard date format for XML generally follows the ISO 8601 specification, which is YYYY-MM-DD (e.g., 2023-10-25). Using the formula =TEXT(A2,"yyyy-mm-dd") ensures maximum compatibility with standard XML systems.
