Dashboard
Where every deduplication project begins.
- Get started quickly with access to help videos and documentation.
- View your recent activity and history of total rows merged by day.
- Access saved Dedupe scenarios to use with other files.
File upload and matching rules
Upload a file to evaluate and select the columns that need to match.
- Deduplicate data from any system that can be exported to a .xlsx or .csv file.
- Find duplicate rows by comparing data in one or more columns.
- Use 20+ exact, fuzzy, and customizable matching algorithms to find matches with similar column values, such as account name acronyms (match H.P. to Hewlett Packard) and nicknames (match Jeff to Jeffrey).
- Employ cross-column matching to find even more duplicates (e.g., compare the values in the Email column against values in the Alternate Email column).
Duplicate results
See which rows are duplicates and merge the data.
- Select the data to retain in each duplicate group manually or in bulk using winner rules.
- Export all duplicate results to a new workbook or text file to see which rows were matched.
- Export the deduplicated data set to a new workbook or text file that includes the original data and winning rows only.
Winning row rules
Decide which row in each duplicate group remains in the spreadsheet.
- Select the winner in every duplicate group with one click using winning row rules, or manually select the winning row in each group.
- Set winning row criteria based on a column value (e.g., keep the row with the lead source column value of website).
- Use one or more conditions to define the winning row based on multiple data attributes.
- Score each condition so the row that meets the most conditions is selected as the winner.
- Save rules for consistent data merging and use in future deduplication projects.
Winning column rules
Define which value is kept for each cell in a column so you never lose important data.
- Set each cell to retain the value from the column in the winning row or create conditions that specify the value to retain. For example, retain the most common value among the duplicate rows.
- Use logic such as custom scoring to rank column values in order of importance, ensuring you keep the right pieces of information for your business.
- Save column rules for faster use on future projects and deduplication consistency.
