Excel Challenges: Data Cleaning and Formatting
Excel Challenge: Dealing with messy or inconsistent data. This includes duplicates, missing values, and formatting issues.
AI Solution: AI-powered tools can automate data cleaning and formatting tasks. They can identify and handle duplicates, fill in missing values, and standardize formatting across the dataset. Tools like Power Query in Excel or external tools that integrate AI can streamline this process.
Imagine you have a dataset with a list of customer names, their contact information, and purchase amounts. The data is messy, containing duplicates, missing values, and inconsistent formatting.
Steps to Clean and Format Data using Power Query
- Open Excel and go to the “Data” tab.
- Go to “Get Data”. Now, click on “From Table/Range”. This will import the data into Power Query.
- In Power Query Editor, you’ll see a preview of your data. Here are the steps to address the challenges:
- To Remove Duplicates:
- Select the “Customer Name” column.
- Click on the “Home” tab. Now, select “Remove Rows,” and then choose “Remove Duplicates.”
- Fill in Missing Values:
- Right-click on the “Contact Number” column, choose “Fill,” and select “Down” to fill in missing values based on the previous row.
- Use the same approach for other columns with missing values.
- Standardize Formatting:
- Click on the “Purchase Amount” column, go to the “Transform” tab, and choose “Format.” You can standardise currency formatting, removing the dollar signs.
- Once satisfied with the changes, click “Close & Apply” to apply the transformations to your Excel worksheet.

Excel Problems for Students: Automated Data Entry
Excel Challenge: Manually entering large amounts of data can be time-consuming and error-prone.
AI Solution: AI-based data entry solutions such as Optical Character Recognition (OCR) technology can automatically extract information from documents. This reduces the risk of human error and accelerates the data entry process.
You have a stack of invoices with supplier information, invoice numbers, and amounts. Manually entering this information into Excel is time-consuming and prone to errors.
Original Data on Invoice:
Invoice Number: INV12345
Supplier: ABC Company
Steps to Automate Data Entry using OCR
- Use a scanner or a camera to capture an image of the invoice.
- Utilise an OCR tool or a service that supports extracting text from images. Popular OCR tools include Tesseract, Microsoft Azure OCR, or Google Cloud Vision API.
- The OCR tool will process the image and extract text. In our example, it will recognize the Invoice Number, Supplier, Date, and Amount.
- Create a template in Excel with columns for Invoice Number, Supplier, Date, and Amount.
- Use the extracted data to populate the corresponding columns.

Natural Language Processing (NLP) for Data Queries
Excel Challenge: Constructing complex queries or pivot tables can be difficult, especially for users with limited SQL or Excel formula knowledge.
AI Solution: NLP-powered tools can understand and process natural language queries and allow users to ask questions in plain English. These tools can then generate the corresponding Excel formulas or queries. This makes it easier for users to interact with and analyse their data.
Assume you have a dataset with columns like Product, Sales, Date, and Region.
Steps to Use NLP for Data Queries in Excel
- Start Excel and import the dataset containing sales data.
- Utilise an NLP-powered Excel add-in or an external tool that integrates with Excel. Tools like Power BI with Q&A (Question and Answer) features or dedicated NLP plugins can be used for this purpose.
- Instead of constructing a traditional Excel formula or SQL query, you can type a natural language query directly. For example, you might type, “Show me the total sales for each product in the last quarter.”
- The NLP tool processes the natural language query, understanding the user’s intent and context.
- The tool translates the natural language query into the corresponding Excel formulas or queries. In this case, it might generate a formula to calculate total sales for each product in the last quarter.
