2026-01-12,41Calculate rolling metrics and period-over-period changes. Requires valid dates or timezone-explicit ISO timestamps and finite numeric values. Dates sort ascending. Resampling uses UTC calendar bins; other tools require unique timestamps. Rolling windows count observations. Forecasts require equal timestamp spacing, use chronological holdout MAE, and provide approximate residual intervals, not guaranteed bounds. Up to 5,000 generated bins or 60 forecast periods.
Prepare the input
Calculate rolling metrics and period-over-period changes.
CSV, TSV and arrays of scalar JSON objects are supported. Identifiers stay text. Empty cells are missing by default; add special missing tokens only if their meaning is certain. Use the sample to inspect the exact workflow.

Keep the useful output
Review the summary and result records. Transformation tools retain separate change, rejected-record or diagnostics datasets where relevant. Choose the dataset before exporting; a report and a cleaned dataset serve different purposes.
CSV exports protect formula-like text. JSON keeps data portable without making an Excel workbook. Reports and editable backups may contain private source values; download only what you intend to share. No automatic account storage or server processing is used.
