Case Study · Lenta
~80 concurrent users, live on ClickHouse
Lenta is one of the largest retail chains in Eastern Europe. Its e-commerce analytics team works with billions of rows of transaction data in ClickHouse — and its analysts work in Excel. Before XLTable, users hit serious limits when working with large data volumes in Excel: exports, extracts, and data duplication were the daily routine.
The solution
XLTable connected Excel directly to ClickHouse through one governed semantic layer — native PivotTables over XMLA, no data duplication, no change to the familiar interface. Excel became the front end; ClickHouse stayed the single source of truth.

In their words
"Before adopting XLTable, our users faced serious limitations when working with large data volumes in Excel. XLTable let us connect Excel directly to ClickHouse without duplicating data and without losing the familiar PivotTable interface.
XLTable helped us lower total cost of ownership by eliminating extra servers and simplifying the development process for analysts.
Deployment took a single working day — no lengthy training, and integration with ClickHouse removes the need for extra database servers and delivers infrastructure savings.
A perpetual XLTable license gives us full control over resources in the long term."
