Key use cases: Microsoft 365 Excel and meinGPT in action

The combination of Microsoft 365 Excel and meinGPT opens numerous practical application possibilities for companies. Here are some of the most important scenarios that show how this integration can improve workflows and create added value.

Automated data analysis and reporting

The challenge: Companies spend a lot of time analyzing Excel data, extracting insights, and creating reports. This process is often tedious, error-prone, and ties up valuable resources.

The solution with Microsoft 365 Excel + meinGPT: A workflow can be configured to automatically respond to new or updated Excel spreadsheets. As soon as data is updated in Excel — for example sales figures or customer statistics — a Make-based trigger can detect this and start the meinGPT workflow.

The workflow reads the Excel data and passes it to a meinGPT process that interprets the data using the selected AI model (e.g., GPT-4o for complex analyses). The AI analyzes trends, recognizes patterns, and identifies anomalies. The workflow then generates a structured analysis report with visualization suggestions, which is automatically created as a document.

Optionally, the result can be written directly back to Excel (in a separate worksheet) or sent as DOCX/PDF to relevant stakeholders.

The main benefit: Time savings of several hours per week by automating recurring analysis tasks. The AI also often provides insights that might be overlooked in manual analysis.

Intelligent data cleansing and enrichment

The challenge: Raw data in Excel is often incomplete, faulty, or inconsistent. Manual cleansing and enrichment is time-consuming and error-prone.

The solution with Microsoft 365 Excel + meinGPT: A meinGPT workflow can be configured to automatically cleanse and enrich Excel records. For example, when a new Excel file with customer data is uploaded, the workflow can be activated to:

Normalize inconsistent formatting (e.g., phone numbers, addresses)
Intelligently complete missing data
Identify and consolidate duplicates
Enrich data with additional information (e.g., industry information for corporate customers)

The combination of native Excel functions such as Power Query and meinGPT’s AI capabilities can be particularly powerful here. For example, the workflow could first perform basic cleansing steps with Power Query and then delegate more complex tasks to the AI.

The main benefit: Drastic improvement in data quality while simultaneously reducing manual effort. Consistent and enriched data leads to better business decisions.

Natural-language data queries and extractions

The challenge: Without in-depth Excel knowledge, it is difficult for many employees to formulate complex data queries or extract specific information from extensive datasets.

The solution with Microsoft 365 Excel + meinGPT: A meinGPT workflow can serve as a natural-language interface to Excel data. Employees can ask simple questions in natural language such as "Show me the top 10 customers by revenue in the last quarter" or "How has product revenue in the North region developed compared to the previous year?".

The workflow translates this request into the corresponding Excel operations (filtering, sorting, pivot tables, etc.) and executes them. The result is summarized again in natural language and can be supplemented with suitable visualizations if needed.

For implementation, the meinGPT workflow would:

1. Process and understand the natural-language request

2. Translate it into the corresponding Excel operations

3. Interpret the results and present them in an understandable format

The main benefit: Democratization of data analysis — even employees without deep Excel expertise can gain valuable insights from complex datasets.

Forecast models and scenario analyses

The challenge: Companies increasingly need forecasting models and scenario analyses for strategic decisions but often lack the necessary data science know-how.

The solution with Microsoft 365 Excel + meinGPT: A specialized workflow can analyze historical Excel data and create various forecasting models. The AI can run through multiple scenarios and simulate the effects of different variables.

The workflow could, for example:

1. Import historical sales data from Excel

2. Identify trends and patterns

3. Create various forecasting models and evaluate their accuracy

4. Select the best model and forecast future sales figures

5. Model alternative scenarios ("what-if" analyses)

For this complex task, the workflow would ideally use a specialized AI model such as GPT-4o, which is optimized for complex reasoning.

The main benefit: Companies can create data-driven future forecasts without having to hire specialized data scientists. The scenarios help with risk assessment and strategic planning.

The use cases mentioned illustrate the potential of integrating Microsoft 365 Excel and meinGPT. Depending on complexity and use case, workflows can be designed differently:

Use case	Complexity level	Setup duration	Maintenance effort	Ideal for
Automated reporting	Medium	1-2 days	Minimal	Finance and controlling teams
Data cleansing and enrichment	Simple to medium	1 day	Occasional adjustments	Data analysts, marketing
Natural-language data queries	Simple	A few hours	Minimal	All employees without Excel expertise
Forecast models	Complex	2-3 days	Regular updates	Management, strategy departments
