Fix Excel Chart Date Axis Changing to Numbers When Pasted in Word
Question details
The user needs to prevent the date-based x-axis of an Excel chart from converting to sequential numbers when copying it to a Word document.

- Product
- Microsoft Excel and Word
- Device & OS
- Mac
- Scenario
- Copying and pasting a chart with a date axis from a spreadsheet into a text document.
- Observed behavior
- The formatted dates on the chart's x-axis unexpectedly change to underlying sequential Excel serial numbers upon pasting into Word.
Ensure both your spreadsheet and document applications are fully updated and restart your device to clear any temporary clipboard glitches before troubleshooting.
Paste the Chart as a Picture
Pasting the chart as an image ensures that all formatting, including the date axis, is preserved exactly as it appears in Excel.
When you paste a chart normally, Word attempts to link or embed the Excel data, which can sometimes cause formatting to revert to default raw values (like Excel's date serial numbers). Converting it to a picture avoids this formatting link entirely.
Open your Excel workbook, click on the chart to select it, and press Cmd+C to copy it.
Navigate to your Word document, click where you want the chart to appear, go to the Home tab, click the arrow below the Paste button, and select 'Paste Special'.
In the Paste Special dialog box, choose 'Picture (TIFF)' or 'Picture (PNG)' and click OK to insert the chart with preserved date formatting.

Transfer Data to a New Workbook
If the issue is isolated to a specific corrupted workbook, moving the data to a fresh file can resolve the formatting glitch.
Update Microsoft Office Apps
Outdated software can cause clipboard compatibility issues between Office applications. Installing the latest updates may fix known bugs.
Prevent Chart Formatting Issues with WPS Office
WPS Office offers a fully integrated suite that handles clipboard actions flawlessly. You can seamlessly copy and paste charts between WPS Spreadsheets and WPS Writer without losing complex formatting like date axes, ensuring your professional reports always look perfect.
- 1. Open your data in WPS Spreadsheets: Launch WPS Spreadsheets, open your document containing the chart, and click on the chart to select it.
- 2. Copy the chart: Right-click the chart boundary and select 'Copy', or use the keyboard shortcut Ctrl+C (Cmd+C on Mac).
- 3. Switch to WPS Writer: Open your target report or document in WPS Writer and place your cursor where the chart should go.
- 4. Paste normally: Press Ctrl+V (Cmd+V on Mac). WPS Office automatically preserves the exact date axis formatting and links the data accurately.

Frequently Asked Questions
Why do my dates turn into sequential numbers when pasting from Excel to Word?
Dates in Excel are internally stored as sequential serial numbers for calculation purposes. When a chart is pasted into Word, the formatting link can sometimes break due to clipboard glitches or software bugs, causing Word to display the raw underlying serial number instead of the formatted date.
Can I format the axis back to dates directly in Word?
Yes, if the chart was pasted as a Microsoft Excel Chart Object. You can select the chart in Word, right-click the horizontal x-axis, select 'Format Axis', navigate to the 'Number' category, and change the format code from 'General' to 'Date'.
Does file corruption cause charting errors between Excel and Word?
Yes. If an Excel workbook has accumulated formatting errors over time (often seen in files used cumulatively over many months), the metadata can become corrupted. Copying the data to a fresh workbook forces Excel to generate clean code, which often resolves the pasting issue.
How can I link an Excel chart to Word so it updates automatically?
To keep the data linked, copy the chart in Excel, go to Word, click 'Paste Special', and select 'Paste Link' along with 'Microsoft Excel Chart Object'. Keep in mind that linking charts is more prone to formatting issues if the source file is moved or corrupted.
