How to Fix Excel Map Charts Not Recognizing Vietnamese Districts
Question details
The user needs to map Vietnamese districts in Excel, but the Map Chart feature fails to recognize and plot certain districts.
- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Creating a district-level geographic map chart for regional data visualization in Vietnam.
- Observed behavior
- Excel fails to match specific Vietnamese districts (e.g., Muong Te District, Ayun Pa), leaving those areas completely blank on the map chart, even though they can be found on the Bing Maps website.
Ensure you have an active, stable internet connection, as Excel Map Charts require online access to retrieve mapping polygons from the Bing Maps service.
Format Geographic Data with Complete Hierarchies
Provide Excel with full geographic context and adjust text formatting to improve the Bing Maps matching algorithm.
Excel relies on the Bing Maps API to interpret geographic text and match it to background mapping polygons. If the name is too ambiguous or contains regional characters that the API struggles to parse, the location will fail to render.
Providing the complete geographic hierarchy (District, Province, Country) and removing diacritics often resolves these matching errors.
Combine your location data into a full string that explicitly states the hierarchy. For example, instead of just typing 'Muong Te', enter 'Muong Te District, Lai Chau, Vietnam'.
Strip out accents and specific Vietnamese alphabetical characters. Use plain English text equivalents (e.g., 'Ayun Pa, Gia Lai, Vietnam' instead of versions with accent marks).
Alternatively, separate your location data into dedicated adjacent columns named 'District', 'Province', and 'Country', then select all three columns when inserting the Map Chart.
Select the newly formatted data range, go to the 'Insert' tab on the Excel ribbon, click 'Maps', and select 'Filled Map' to force Excel to query Bing Maps again.
Report Missing Mapping Polygons to Microsoft
Submit a bug report directly to the Excel development team if Bing Maps lacks the specific district polygon boundaries.

Frequently Asked Questions
Why does the Bing Maps website find my district, but Excel Map Charts does not?
Excel Map Charts rely entirely on specific polygon records (geometric boundaries) provided by the Bing Maps API to color an area. The public Bing Maps website often uses a broader database that includes point data (just a pin on the map). If the boundary polygon for a district hasn't been coded into the API, Excel cannot draw the map area.
Should I use local Vietnamese language or English for Excel Map Charts?
Generally, using standard English geographic suffixes (like 'District' or 'Province') alongside the local name without diacritics yields the highest match rate. The Excel mapping API sometimes struggles to parse specific local character encodings and accents correctly.
Are there alternative ways to plot unrecognized locations in Excel?
Native Excel Map Charts cannot map areas if the Bing API lacks the boundary data. As a workaround, you can try using the '3D Maps' (Power Map) feature in Excel, which sometimes uses different geocoding logic, or you can roll your data up to the provincial level instead of the district level, which generally has broader geographic support.
