Group Longtail Values
Infoveave Data Automation — Aggregation & Grouping
Keep the categories that matter. Collapse everything else into Others. No filters to maintain, no formulas to rebuild.
Categorical columns in real datasets are messy — hundreds of brands, hundreds of product types, hundreds of supplier codes. When you visualize them, the chart becomes unreadable and your key categories get lost in the noise. Group Longtail Values fixes this automatically inside your workflow: you define the categories that matter, and everything else collapses into a single label on every run.
What Group Longtail Values does
Replace low-frequency or off-list categories with a single label like Others inside your Infoveave workflow. Cleans long-tail noise from charts and reports without manual filtering.

When to use Group Longtail Values
- Your column has dozens or hundreds of distinct values but you only care about the top 3–10 categories for reporting
- A chart or dashboard is cluttered with low-frequency entries that distract from the key trends you want to highlight
- You need to normalize a product, brand, or supplier column to a fixed allowed set before aggregating or pivoting
- You want to reduce cardinality in a column before feeding it into a machine learning feature set or grouping step
When to avoid it
- You need to understand the long-tail entries rather than collapse them — explore with Count Occurrences first
- You want to filter out low-frequency rows entirely instead of relabeling them — use Filter on Values instead
- Your allow list changes frequently — consider using a Static Lookup table instead for easier maintenance

How teams use Group Longtail Values
Real scenarios where this transformation saves hours of manual work.
Simplify Brand Distribution Charts
A retail analytics team has 200+ brands in their product catalog but wants charts that highlight only Apple, Samsung, and Google. Group Longtail Values runs on every catalog import and collapses the remaining brands into Others — keeping every visualization clean without manual filtering.
Normalize Supplier Codes for Procurement Reporting
A procurement team tracks spend across hundreds of supplier codes, but monthly dashboards focus on the top 10 strategic suppliers. Group Longtail Values consolidates everything outside that list into a single Others row — making procurement trend analysis straightforward.
Consolidate Cost Centre Codes for Executive Summaries
Finance teams report spend across dozens of cost centres but executive dashboards only show the five largest. Group Longtail Values automatically collapses the remaining codes into an Others bucket on every GL extract, keeping the summary accurate and uncluttered.

Configuration
Key fields to configure in the Infoveave workflow builder. Full reference available in the documentation.
Column Name
The categorical column you want to clean. Select the column whose values you want to consolidate — such as brand, product type, supplier code, or cost centre.
Allow List
The set of values you want to keep exactly as they are. Any value found in the column that does not appear in this list will be replaced by the Replacement Value. The allow list is case-sensitive.
Replacement Value
The label that replaces every value outside the allow list — typically Others, Misc, or Unknown. Choose something meaningful for your reporting context so downstream charts and dashboards stay interpretable.
