Why Developers Need AI‑Powered Spreadsheet Queries In modern data‑driven apps, users expect instant answers—not just raw files. Traditional Excel processing requires manual formulas or cumbersome LINQ queries. Sheetize AI bridges that gap:

Pain PointWhat Happens Without Sheetize AI
Manual Look‑upsTeams spend hours writing VLOOKUPs or pivot tables to answer simple “how many” questions.
Inconsistent DataDifferent developers implement ad‑hoc parsers, leading to bugs and duplicated logic.
Scalability LimitsQuerying large CSVs or XLSX files with pure .NET code can hit memory or performance bottlenecks.
User Experience GapEnd‑users must export the file to another tool (Power BI, Tableau) to get insights.
Solution: Sheetize AI .NET SDK – ask a question in plain English (or any supported language) and receive a structured answer (JSON, DataTable, or POCO) directly from the spreadsheet file.

Core Benefits at a Glance

FeatureBenefits
Natural‑Language QueriesNo need to know the exact column names or write complex LINQ; just ask “What was the total sales for Q2?”
Multi‑Format SupportWorks with XLSX, XLSB, CSV, XML, and even password‑protected workbooks.
Scalable EngineStreams data, and can be run inside micro‑services.
Secure & OfflineAll processing stays on‑premises; no data leaves your environment.

Asking a Question – 5‑Line Sample (XLSX → Answer)

using Sheetize.AI;

string ApiKey = "";
string ApiUrl = "https://llm.professionalize.com/v1/chat/completions";

Configuration.Model = Model.Recommended;
SheetizeAI sheetizeAI = new SheetizeAI(ApiKey, true, ApiUrl);

string result = await sheetizeAI.SpreadsheetQuestion("D:\\Sample.xlsx", "How many nights Christopher Wright will work?");
Console.WriteLine(result);

// Alternative: Using TextWriter to write to the console instead of using Console.WriteLine

TextWriter writer = Console.Out;
await sheetizeAI.SpreadsheetQuestion("D:\\Sample.xlsx", "How many nights Christopher Wright will work?", writer);
