The "Online VLOOKUP" Tool for Excel & CSV
Stop struggling with complex Excel formulas like =VLOOKUP, =XLOOKUP, or =INDEX(MATCH).
OmniFlowKit provides a free way to compare two Excel sheets and extract matching rows instantly.
Why use this instead of Excel?
Comparing two files in Excel requires complicated formulas. One trailing space (e.g., "ID 123 ") can break the entire lookup. Our tool handles fuzzy matching automatically.
Common Use Cases
- Compare Two Sheets: Find which rows in Sheet A exist in Sheet B.
- Filter Email Lists: Upload a "Do Not Contact" list and filter your master list.
- Product Matching: Extract product details using a list of SKUs.
- School/Employee Data: Extract records for specific IDs from a master database.
How to Extract Matching Rows
- Upload Source Files: Upload your "Master File" (the full dataset) and your "Reference List" (the items you want).
- Select Sheets: If your Excel file has multiple tabs, use the dropdown to pick the correct one.
- Map Columns: Select the matching column (e.g., "Student ID" matches "ID Number").
- Download: Click "Extract". We perform an inner join and give you a clean Excel file.
