What are the limits of Time-Series Resampler?
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. Inputs stay in browser memory. No workbook is created. Table limits: 5 MB total text, 25,000 rows, 64 columns and 200,000 cells; expensive operations have stricter limits. Processing can be cancelled.
