📝 TL;DR
Combine OData filtering with Filter array in Power Automate for precise, case-sensitive SharePoint queries.
💡 Challenge
SharePoint OData filtering does not differentiate between uppercase and lowercase letters.
✅ Solution
Use OData filtering for an initial, quick query. Then, refine the data using the “Filter array” action, which does distinguish between uppercase and lowercase characters.
🔧 How It’s Done
Apply OData filtering in your SharePoint query for the first selection (e.g., based on a specific field value). Follow it up with the “Filter array” action to perform a case-sensitive check by filtering the text again in the array.
🎉 Result
You get fast and efficient filtering with OData, combined with precise, case-sensitive verification using “Filter array.” This ensures you retrieve exactly the data you’re looking for.
🌟 Key Advantages
🔸 Fast queries with OData 🔸 Accurate filtering with “Filter array” 🔸 Combined efficiency and precision

🛠️ FAQ
1. Why is OData filtering case-insensitive?
SharePoint’s OData endpoint applies string comparisons without distinguishing letter casing.
2. Can I perform case-sensitive filtering directly in OData?
No, SharePoint OData does not support native case-sensitive comparisons in the query.
3. Does using Filter array impact performance?
When used after OData pre-filtering, Filter array processes a smaller set in-memory, maintaining good performance.
