What's New in Jetti Sheets

A timeline of how Jetti Sheets has evolved-from early development to where we are today.

v1.12.1 - Smarter Segments & Faster Cold Starts

Duration labels auto-fill so you never see blank cells. Compact pill sizing and segment tip line improve layout clarity.

Highlights

  • Duration fallback labels - Monthly for recurring, One-time for trials, fees, and retail.
  • Compact pill sizing and segment tip line for cleaner layout.
  • sourceRange auto-expansion - materialized columns now included in report data range.

February 20, 2026 - Product Updates

Combined release notes for 5 updates shipped on February 20, 2026.

v1.12.0 - Smart Segment Detection

Messy free-text columns just became usable. The new Segment Engine classifies values like "90 Day Pass" and "Annual Commitment" into clean groups - Plan Type, Duration, Price, and more.

Highlights

  • Purple dashed pills in the column mapping dialog for segment-derived dimensions.
  • Source labels and coverage badges show where segments come from and how much they cover.
  • Best category pre-selected; Duration and Price available as opt-in.
  • Click Apply and Jetti Sheets writes new segment columns directly into your sheet.
  • Validated keyword database covering 20 categories with 99%+ accuracy.

v1.11.0 - Visualize Your Reports

The new Visualize option in the Explore tab lets you see your report data as interactive charts - right in the sidebar.

Highlights

  • Cohort build-up: Stacked bar and Layer Cake (stacked area) with teal→blue year-banded gradient.
  • Cohort retention: Clean line charts with automatic percentage formatting and Last 6/12/24 presets.
  • Snowball: Stacked flows with Net Change reference line.
  • Copy as presentation-ready image - title, subtitle, legend, and crisp axes included.
  • Expand any chart into a larger modal view for detailed exploration.

v1.10.0 - Polished Onboarding

The license activation screen has been completely redesigned - a clean, single screen with the Jetti Sheets logo, your license input, and a clear path to get started.

Highlights

  • Single-screen activation - no more multi-step carousel.
  • Animated success confirmation before the sidebar loads.
  • In-app support accessible right from the activation screen.

v1.9.1 - Smart Formatting Presets

Cohort reports now look great out of the box. Select Customer Retention or Value Retention and Jetti Sheets auto-applies the optimal layout and gradient.

Highlights

  • Customer Retention: left-aligned, normalized to %, heatmap gradient.
  • Value Retention: right-aligned calendar view, absolute values, green gradient.
  • MRR floor clamps negative customer-month balances to $0.

v1.9.0 - MRR Mode for Prepaid Plans

Jetti Sheets detects prepaid and annual plans and offers two lenses: Revenue (when cash arrived) and MRR (monthly run-rate). A $120 payment for a 90-day plan becomes ~$40/month.

Highlights

  • Automatic detection of prepaid patterns with a toggle card in the config tab.
  • Revenue vs MRR - switch between raw cash flow and monthly run-rate.
  • Smart parsing: clean duration columns, embedded text patterns, member rate inference.
  • Works with cohort, snowball, and insights.

v1.8.0 - Simple Prompt Templates

Two new AI templates: "Am I Ready To ___?" for business decision advice, and "Explain It Simply" for plain-language summaries of your reports.

Highlights

  • Currency symbol auto-detection from sheet formatting.
  • Time period flows into prompt metadata for more accurate analysis.

v1.7.0 - Context-Aware Sidebar

The sidebar now knows which sheet you're on. Sheet name indicators, source sheet suggestions, and report card highlights help you navigate faster.

v1.6.0 - Streamlined Config

The config tab is cleaner: two-mode flow (idle → resolved), better UX copy, and a debounced generate button.

v1.5.0 - Multi-Account Fixes

Better handling of multiple Google accounts in one browser - clearer auth guidance, multi-account redirect loop detection, and admin-blocked escape hatch.

Highlights

  • Safari and token refresh errors get clear guidance instead of confusing errors.
  • Sidebar shows which Google account Jetti Sheets is running as.
  • Workspace admin hint if organization blocks required permissions.

v1.4.7 - Wide Format Fix

Fixed auto-detect mistakenly treating ISO 8601 timestamps in column headers as wide-format date columns.

v1.4.6 - Smarter Auto-Detect

Auto-detect kept switching your output format without asking. Now your "Periods as Columns" vs "Periods as Rows" choice stays put.

Highlights

  • License activation is faster-keys are captured more quickly after purchase.
  • Friendlier guidance if you try to activate before processing completes.

v1.4.5 - Recent Uploads Fix

Selecting a file from "Recent Uploads" was failing. Fixed-your previously uploaded CSVs are accessible again.

v1.4.4 - Payments Go Live

The payment system is now fully operational. License purchases and activations work end-to-end.

Highlights

  • Clearer error messages-device limit reached, connection issues, or invalid key each tell you exactly what to do next.

v1.4.1 - Large File Uploads

Files over 32MB were failing silently. Now they upload without issues.

January 23, 2026 - Product Updates

Combined release notes for 2 updates shipped on January 23, 2026.

v1.4.0 - Enhanced Privacy

Jetti Sheets now only accesses the spreadsheet where it's installed-not your entire Google Sheets library. Fewer permissions, more control over your data.

v1.3.0 - Report Queue

Run up to 3 saved reports as a batch. A new queue interface shows real-time progress for each report-pending, running, completed, or failed.

v1.2.0 - Performance Boost

Cohort reports: 12-15 seconds → 3 seconds. Snowball reports: now 4-5 seconds. The platform handles more concurrent users smoothly.

v1.1.0 - Polish & Refinements

Small but meaningful improvements across the board.

Highlights

  • Click a cell that can't be analyzed? Helpful guidance instead of a confusing error.
  • Cache expired? A clean modal with a "Regenerate Report" button.
  • Subscription reset dates and emails now display correctly in the sidebar.

v1.0.0 - Launch

Jetti Sheets launches on the Google Workspace Marketplace. Turn raw customer and revenue data into cohort analysis, revenue waterfalls, and interactive drill-downs-without leaving Google Sheets.

  • Interactive Drill-Down: Click any cell to see the customers behind the numbers
