Smart Excel Numbering & Sequence Automation: SKIP, 42/100 | Ideas Lab

Excel add-in that automates numbering and sequence generation for users who currently use manual formulas or copy-paste.

The pain

Excel users spend time manually creating sequences, numbering rows, or building formulas for auto-increment across merged cells. This is repetitive, error-prone, and breaks when data changes. The built-in tools (fill series, formulas) require setup knowledge and don't handle edge cases like merged cells well.

The gap

Excel has fill-down and formula tools, but they require user knowledge and don't work smoothly with complex layouts. A templated add-in could reduce setup time from 5 minutes to 30 seconds. The gap exists but is small, this solves a friction point, not a broken workflow.

Build angle

Start by validating which specific use cases cause the most friction. Interview 20 Excel power users about their numbering workflows. Build a minimal add-in that handles the top 3 use cases (simple row numbering, sequence with step, numbering across merged cells). Charge $2-5/month or $20 one-time. Distribute through AppSource and Reddit Excel communities.

Strengths

Clear, specific problem with measurable time savings
Low technical barrier to build (Excel VBA/JavaScript API)
Existing distribution channel (Microsoft AppSource)
Recurring revenue potential if positioned as subscription
Low CAC if marketed to Excel communities and forums

Risks

Market size is narrow, only power users and data entry teams feel real pain; casual users use built-in tools
Microsoft could add this feature natively in Excel, eliminating the market overnight
Adoption friction: users must install add-in, trust it, and change habits
Monetization is hard, users expect free or $1-2 tools; willingness to pay is low
Competition exists (Kutools for Excel, other add-ins); differentiation unclear
Validation signal is weak, Google Trends suggestion doesn't prove demand, only search volume

Is the pain real, is there a gap, is it the right time, can one person build it.

No easy way to hide Instagram stories from specific groups like coworkers

Instagram lacks a reverse 'close friends' feature to quickly hide stories from select people (e.g., colleagues) without hiding from everyone.
