Follow these steps to streamline your workflow and enhance operational efficiency in your role.
Start Here
Step 1: Gather and Upload Raw Data
Prompt: "I have raw client data in various formats (e.g., CSV, Excel). What is the best way to upload and centralize this data for cleaning and analysis?"
Goal
Centralize all relevant raw data files into a single repository or platform where automated cleaning can be executed efficiently.
Example
I have quarterly sales data in three Excel files and a separate CSV with client contact records. How do I prepare and upload them for the cleaning workflow?
Variations
- How do I connect my Google Sheets data to the automated cleaning system?
- Can I import files from Dropbox or SharePoint into the analysis tool?
- What’s the most efficient way to upload zipped files for bulk import?
Troubleshooting
- File format errors: Convert all files to supported formats such as CSV or XLSX before uploading to avoid compatibility issues.
- Missing headers or inconsistent columns: Standardize column headers and order before import or use the chatbot to suggest alignment strategies.
Step 2
Step 2: Define Data Cleaning Requirements
Prompt: "Analyze my uploaded files and suggest data cleaning steps needed. Remove duplicates, handle missing values, and standardize formats."
Goal
Specify and customize the set of cleaning operations relevant to your analysis goals, such as deduplication, normalization, and handling missing or inconsistent data.
Example
Review my client contact file for any duplicate entries, highlight rows with missing email addresses, and ensure all phone numbers follow the (XXX) XXX-XXXX format.
Variations
- Apply outlier detection and flag suspicious transactions.
- Change all date formats to YYYY-MM-DD.
- Remove rows where the "Status" column is blank.
Troubleshooting
- Unclear requirements: Review company documentation or previous analysis to clarify standards, or ask the AI for recommended best practices.
- Complex cleaning logic: Break complex conditions into smaller prompts, or seek help with appropriate formulas or scripts.
Step 3
Step 3: Execute Automated Cleaning Workflow
Prompt: "Run the automated cleaning workflow using the parameters I specified. Provide a summary of the changes made and flag any unresolved issues."
Goal
Trigger the cleaning automation process while monitoring results to ensure that all specified requirements are correctly implemented, and unresolved data issues are flagged for review.
Example
After deduplication and standardization, show me how many records were removed or altered and list any rows where critical fields remain incomplete.
Variations
- Show a preview of the cleaned data before finalizing changes.
- Export changes log as a separate report for documentation.
Troubleshooting
- Partial automation failure: Review AI logs for errors and rerun specific steps if needed. Contact support if issues persist.
- Discrepancies in cleaned data: Compare before-and-after datasets to identify unexpected changes; adjust parameters or rules as needed.
Step 4
Step 4: Export and Document Cleaned Data
Prompt: "Export the cleaned dataset in Excel and CSV formats. Generate a log or summary report explaining the cleaning actions taken."
Goal
Create finalized, portable cleaned datasets along with documentation supporting data integrity and compliance for further analysis or sharing with stakeholders.
Example
Provide the cleaned client contacts as cleaned_contacts.xlsx and cleaned_contacts.csv, plus a PDF summary of all automated cleaning operations applied.
Variations
- Save and version the output file to a specified cloud drive.
- Embed the cleaning report in an email to the project team.
Troubleshooting
- File export errors: Double-check file paths and permissions. Try exporting in an alternative format if needed.
- Missing logs or documentation: Request the AI to regenerate the cleaning summary, or check previous task runs for existing documentation.
