The dedupe dialog, before removing repeats.
Remove duplicate rows
1
Open Dedupe
Open a column’s header menu and choose Dedupe, or open Table settings and use the Deduplication section.
2
Pick the column to match on
Choose the column under Duplicate on. Rows with the exact same value in that column count as duplicates, and blank cells never match each other.
3
Confirm the count
The dialog names how many rows it will remove before you commit, keeping the first of each repeated group and deleting the rest.
Split a column into parts
1
Choose a delimiter
Open a column’s header menu, choose Text to columns, and pick Space, Comma, Semicolon, Tab, or Custom… for your own character, under Split on.
2
Set how many columns
Set Columns to how many parts you expect. The preview updates as you adjust it.
3
Create the columns
New columns are added beside the original, which is left untouched. They stay live, so they re-split if the source cell changes.
Merge two columns
Add Merge columns from the catalog, choose the columns to combine under Source columns, and set a Separator to sit between their values. Turn on Skip empty values to avoid a dangling separator where one side is blank.Give a nested field its own column
An enrichment result that holds more than one field, like an address, can hand any one of them its own column. Open the field from a column’s header menu or its cell drawer. Choose Give a field its own column…, or Give this field its own column from the drawer icon. Choose Create a new column to add one linked to the parent. It recomputes when the parent does, and you can rename it like any other column. Use an existing column overwrites that column’s values instead, and cannot be undone.Good to know
Can dedupe match on more than one column at a time?
Can dedupe match on more than one column at a time?
No, one column per run. Run it again on a second column to narrow further.
Is removing duplicate rows the same as an automatic dedupe on new rows?
Is removing duplicate rows the same as an automatic dedupe on new rows?
No. This is a one time cleanup you trigger yourself, not a standing rule that catches every row that arrives afterward.
Can I undo a dedupe?
Can I undo a dedupe?
A short window right after removal lets you undo it, the same as any row delete. Past that, the rows are gone for good.
Is there a limit on how many duplicate rows I can remove at once?
Is there a limit on how many duplicate rows I can remove at once?
A very large batch may need running twice. The dialog tells you if it only cleared part of the table, so you can run it again for the rest.
What column types can't be split, merged or deduped?
What column types can't be split, merged or deduped?
A column holding a list or a nested object has no single value to compare or split, so Dedupe and splitting are unavailable on it.
Does giving a field its own column cost credits?
Does giving a field its own column cost credits?
No. The new column reads a value the enrichment already fetched, so it has nothing new to compute.
