How to Fix SharePoint Formula Syntax Not Supported Errors
Question details
The user is trying to resolve a syntax error in SharePoint Online where a formula functions correctly on one site or in a desktop spreadsheet application but fails on another site.
- Product
- SharePoint Online / Excel
- Device & OS
- not provided
- Scenario
- Using or copying formulas across different SharePoint sites with differing locale configurations.
- Observed behavior
- The formula produces a 'syntax not supported' error on specific SharePoint sites despite containing valid logic.
Verify that your formula logic works perfectly in a standard spreadsheet application before troubleshooting the site-specific settings in SharePoint.
Adjust Site Regional Settings and Modify Formula Separators
Check the SharePoint site's locale configuration and update your formula separators (commas or semicolons) to match those regional requirements.
SharePoint Online formulas rely on the regional settings of each specific site. Depending on the locale, the system may require a semicolon (;) instead of a comma (,) to separate formula arguments.
Matching your formula separators to the site's regional settings is the standard method to resolve syntax errors without rewriting the formula logic.
Navigate to the affected SharePoint Online site. Click on the gear icon in the top right corner and select 'Site information', then click 'View all site settings'.
Under the 'Site Administration' section, click on 'Regional settings'. Note the current Locale selected for the site.
If the site uses a European locale (where decimals are commas), replace all commas (,) in your formula with semicolons (;). If it uses a US/UK locale, replace semicolons with commas.
Paste the updated formula back into your SharePoint list or column settings and save the changes to verify the syntax error is resolved.
Use WPS Spreadsheet for Seamless Formula Management
While SharePoint handles online lists, WPS Office provides a highly compatible and lightweight alternative to Microsoft Excel for local spreadsheet processing. It offers advanced formula auditing tools, allowing you to build, test, and troubleshoot complex formulas easily before deploying them online.
- 1. Install WPS Office: Download and install the free WPS Office suite on your computer.
- 2. Draft Your Formula: Open WPS Spreadsheet, create a new workbook, and build your formula logic locally.
- 3. Verify and Adapt: Ensure the formula functions correctly, then copy it to SharePoint, adjusting commas or semicolons according to your site's regional settings.
Frequently Asked Questions
Why do formula separators change between different SharePoint sites?
SharePoint uses the regional locale settings of each individual site to determine its formatting rules. Some regions use a comma as a decimal mark, which forces the system to use a semicolon to separate formula arguments instead.
Can I change the regional settings of a SharePoint site?
Yes, if you have sufficient permissions, you can change the locale by navigating to Site Settings > Regional Settings and choosing a locale that aligns with your preferred formula structure.
How do I test my formula syntax before using it in SharePoint?
You can build and test your formulas in desktop spreadsheet applications like WPS Spreadsheet first. Once the logic works, simply copy the formula and adapt the separators (commas or semicolons) as required by your specific SharePoint site.
