In our Chartered Accountancy practice, clients routinely send us messy, inconsistent data: PDF bank statements, CSV exports, JSON ledgers, or raw Tally dumps. Standardising this raw data for reconciliation, GST filing, or TDS compliance is repetitive and time-consuming.
Power Query in Excel (Get & Transform) allows us to define data-cleaning workflows once and reuse them every month with a simple Refresh—saving hours of manual labor and ensuring consistent output every time.
🛠 What Power Query Offers Chartered Accountants
Based on tools like Excel University, ICAI AI Lab, and Chandoo.org, Power Query enables:
- Point-and-click data extraction and transformation (no complex VBA needed)
- Join and merge messy records to identify mismatches
- Combine monthly files with the "From Folder" option
- Handle formats like PDF, CSV, JSON, Excel, and web links
- Enable consistency, audit trails, and repeatable processes
💡 Real Use Cases from Our CA Practice

📥 Sales/Purchase Data for GSTR Filing
