TroubleshootingPeak Leakage
Why doesn't Peak Leakage accept my CSV?
Peak needs a column with the month and one column per metric, or the three columns month, metric and value. Months can be 2026-08, 08/2026 or Aug 2026. Columns whose names Peak can't map to a metric are listed and skipped. Download the template under “Data” and the names will match.
