Why Typing 40 Shows Up as 4000% in Excel

September 15, 2026 by zelobiz
Why typing the number 40 into a percentage-formatted Excel cell shows 4000 percent

Percentage formatting multiplies whatever’s stored by 100 for display. Type a plain number instead of the percent sign, and the math still runs, just on the wrong starting value.

Excel’s FILTER Function: The #CALC! Mistake Nobody Explains

September 15, 2026 by zelobiz
Excel's FILTER function syntax and its two distinct error types

FILTER’s #CALC! and #SPILL! errors look similar but mean opposite things: one is about nothing matching, the other is about matches with nowhere to land.

September 15, 2026 by zelobiz
How to unhide rows in Excel, including the special case of row 1

The normal right-click method needs a visible row on both sides of the hidden one. Row 1 has no row above it, which is exactly why it needs a different fix.

Index Match Excel: The Real Reason It Survives a Column Insert

September 14, 2026 by zelobiz
Why INDEX MATCH survives an inserted column when VLOOKUP breaks

VLOOKUP trusts a number typed once and never rechecked. INDEX/MATCH searches for the column by name every time, which is the specific reason it survives an inserted column and VLOOKUP doesn’t.

XLOOKUP vs VLOOKUP: The Real Difference Nobody Mentions

September 14, 2026 by zelobiz
XLOOKUP versus VLOOKUP comparison and Excel version compatibility

XLOOKUP searches any direction and defaults to exact match. It’s also completely absent from Excel 2016 and Excel 2019, a compatibility gate most comparisons skip entirely.

The VLOOKUP Mistake That Breaks a Column With No Error

September 14, 2026 by zelobiz
Why inserting a column into a VLOOKUP table array returns the wrong value

VLOOKUP’s col_index_num is a number typed once and never rechecked. Insert a column anywhere inside the range, and it silently returns the wrong value with no error at all.

Reading the Real Limit Behind Any AI Tool’s Free Plan

September 13, 2026 by zelobiz
The headline monthly limit versus the real constraint behind two AI tools' free plans

A monthly total is rarely the whole story. Two independently verified AI tools both show the same pattern: the real limit is a second detail the headline figure doesn’t mention.

Otter.ai’s Free Plan: The Per-Meeting Cap That Matters More

September 13, 2026 by zelobiz
Otter.ai's free plan monthly minute total versus its per-meeting cap

September 13, 2026 by zelobiz
Grammarly's pricing page and support article describe different plan structures

Grammarly’s AI Prompt Limits: 100, 2,000, or Unlimited

September 13, 2026 by zelobiz
Grammarly's current AI prompt limits by plan and how the monthly reset actually works

Grammarly’s own pricing page lists exact numbers by plan. What it doesn’t make obvious is that the monthly refill date is tied to your account’s own history, not the calendar.
