+
+## What "Office" Means Here
+
+Productivity software: Microsoft 365, Google Workspace, and office administration.
+
+| Signal | Context | Load |
+|--------|---------|------|
+| Formulas, pivot tables, VLOOKUP, macros | Spreadsheets | `tools/spreadsheets.md` |
+| Formatting, headers, mail merge, TOC | Documents | `tools/documents.md` |
+| Slides, animations, presenter view | Presentations | `tools/presentations.md` |
+| Supplies, vendors, facilities, space | Office admin | `admin/facilities.md` |
+
+---
+
+## Spreadsheets (Excel / Google Sheets)
+
+**Formulas people actually need:**
+- `VLOOKUP` / `XLOOKUP` — lookup value in table, return another column
+- `SUMIF` / `COUNTIF` — sum/count with conditions
+- `INDEX/MATCH` — more flexible than VLOOKUP
+- `IF` with `AND`/`OR` — conditional logic
+
+**Common problems:**
+- VLOOKUP returns #N/A → check for spaces, data types, exact match setting
+- Formula works in one cell, breaks when copied → missing `$` for absolute references
+- Dates sorting wrong → format as actual dates, not text
+
+**Pivot tables:** Right-click data → Create Pivot Table → drag fields to rows/columns/values.
+
+---
+
+## Documents (Word / Google Docs)
+
+**Formatting essentials:**
+- Use Styles (Heading 1, 2, 3) for structure — enables automatic TOC
+- Page numbers starting on page 3: Insert break → Different First Page → start numbering
+- Different headers per section: Section breaks, unlink from previous
+
+**Mail Merge:**
+1. Prepare data source (Excel with columns: Name, Address, etc.)
+2. Word → Mailings → Start Mail Merge → Letters
+3. Insert Merge Fields where dynamic content goes
+4. Preview Results → Finish & Merge
+
+---
+
+## Presentations (PowerPoint / Google Slides)
+
+**Professional basics:**
+- Slide Master for consistent styling (View → Slide Master)
+- 6x6 rule: max 6 bullets, 6 words per bullet
+- One idea per slide
+
+**Animations:**
+- Entrance animations for bullet reveal (Appear > Fade > Fly In)
+- Timing: On Click vs After Previous
+- Keep it subtle — animation should aid, not distract
+
+**Presenter View:** F5 to present, use Presenter View to see notes while audience sees slides.
+
+---
+
+## Office Administration
+
+For those managing physical office operations:
+
+**Supplies & Inventory:**
+- Track with simple spreadsheet: Item, Quantity, Reorder Point, Supplier
+- Set calendar reminders for regular orders
+- Bulk ordering usually 15-30% cheaper
+
+**Vendor Management:**
+- Cleaning, maintenance, IT support contracts
+- Document SLAs and contact info in shared location
+- Review contracts annually for renegotiation
+
+**Space Planning:**
+- Hot-desking: Use booking system (even a shared calendar works)
+- Meeting room: Clear naming, visible displays, 15-min buffers
+
+---
+

+# Documents Deep Dive
+
+## Structure with Styles
+
+**Why use Styles:**
+- Automatic Table of Contents
+- Consistent formatting throughout
+- Easy global changes (change Heading 1 once, all update)
+
+**Hierarchy:**
+- Title → document name
+- Heading 1 → major sections
+- Heading 2 → subsections
+- Heading 3 → sub-subsections
+- Normal → body text
+
+**Modify Style:** Right-click style → Modify → Change font, spacing, color
+
+---
+
+## Page Layout
+
+### Section Breaks
+- Use for different headers/footers in parts of document
+- Insert → Break → Section Break (Next Page)
+- Unlink sections to have different content
+
+### Page Numbers
+**Start on page 3:**
+1. Insert Section Break before page 3
+2. Double-click footer on page 3
+3. Uncheck "Link to Previous"
+4. Insert Page Number → Format → Start at 1
+
+### Different First Page
+- Design → Different First Page (checkbox)
+- First page can have no header, rest have header
+
+---
+
+## Mail Merge
+
+**Use cases:** Personalized letters, labels, envelopes, emails
+
+**Process:**
+1. **Data source:** Excel file with columns (Name, Address, etc.)
+2. **Main document:** Template with placeholders
+3. **Merge:** Combine to produce individual documents
+
+**Steps (Word):**
+1. Mailings → Start Mail Merge → Letters
+2. Select Recipients → Use Existing List → select Excel file
+3. Insert Merge Fields where personalization needed
+4. Preview Results to check
+5. Finish & Merge → Edit Individual Documents (or Print)
+
+**Conditional content:**
+```
+{IF {MERGEFIELD Gender} = "M" "Mr." "Ms."}
+```
+
+---
+
+## Formatting Fixes
+
+| Problem | Solution |
+|---------|----------|
+| Paragraph spacing inconsistent | Select all → set Before/After spacing explicitly |
+| Tab stops not aligning | View ruler → clear tabs → set new tab stops |
+| Images jumping around | Right-click image → Wrap Text → choose wrap style |
+| Page breaks in wrong places | Insert manual Page Break where needed |
+| Table breaking across pages | Table Properties → Row → uncheck "Allow row to break" |
+
+---
+
+## Tables
+
+**Convert text to table:** Select text → Insert → Table → Convert Text to Table
+**Repeat header row:** Table Properties → Row → Repeat as header row
+**Resize columns:** Double-click column border to auto-fit
+
+---
+
+## Track Changes
+
+**Enable:** Review → Track Changes
+**Accept/Reject:** Review → Accept/Reject buttons
+**Compare documents:** Review → Compare → select original and revised
+
+---
+
+## Keyboard Shortcuts (Word)
+
+| Action | Windows | Mac |
+|--------|---------|-----|
+| Heading 1 | Ctrl+Alt+1 | Cmd+Option+1 |
+| Heading 2 | Ctrl+Alt+2 | Cmd+Option+2 |
+| Page break | Ctrl+Enter | Cmd+Enter |
+| Find & Replace | Ctrl+H | Cmd+H |

+# Presentations Deep Dive
+
+## Slide Design Principles
+
+**Content rules:**
+- One idea per slide
+- 6x6 rule: max 6 bullets, max 6 words per bullet
+- Headlines tell the story (someone skimming titles should get the point)
+- Use images over text when possible
+
+**Visual hierarchy:**
+- Title: largest, top
+- Key point: prominent
+- Supporting details: smaller, less prominent
+- Source/footnote: smallest, bottom
+
+---
+
+## Slide Master
+
+**What it does:** Defines default layouts, fonts, colors, logo placement.
+
+**Access:** View → Slide Master
+
+**Changes here apply to all slides:**
+- Add company logo to master = appears on all slides
+- Change title font = all titles update
+- Set background = consistent throughout
+
+**Multiple layouts:** Create different masters for title slides, content slides, section headers.
+
+---
+
+## Animations
+
+### Types
+- **Entrance:** How element appears (Fade, Fly In, Appear)
+- **Exit:** How element disappears
+- **Emphasis:** Draw attention (Pulse, Grow/Shrink)
+- **Motion Path:** Move element along path
+
+### Best Practices
+- Subtle over flashy (Fade > Bounce)
+- Consistent animation style throughout
+- Purpose: guide attention, not entertain
+- Test timing before presenting
+
+### Build Effect (Bullets one by one)
+1. Select text box
+2. Animations → Add Animation → choose effect
+3. Effect Options → By Paragraph
+4. Set to "On Click" or "After Previous"

+## Formula Patterns
+
+### Lookup Values
+```
+=VLOOKUP(lookup_value, table_range, column_index, FALSE)
+=XLOOKUP(lookup_value, lookup_array, return_array)  [Excel 365+]
+=INDEX(return_range, MATCH(lookup_value, lookup_range, 0))
+```
+
+### Conditional Calculations
+```
+=SUMIF(range, criteria, sum_range)
+=SUMIFS(sum_range, criteria_range1, criteria1, criteria_range2, criteria2)
+=COUNTIF(range, criteria)
+=AVERAGEIF(range, criteria, average_range)
+```
+
+### Text Manipulation
+```
+=CONCATENATE(A1, " ", B1)  or  =A1 & " " & B1
+=LEFT(text, num_chars)
+=RIGHT(text, num_chars)
+=TRIM(text)  -- removes extra spaces
+=PROPER(text)  -- Title Case
+```
+
+### Date Functions
+```
+=TODAY()
+=YEAR(date) / MONTH(date) / DAY(date)
+=DATEDIF(start_date, end_date, "Y")  -- years between dates
+=WORKDAY(start_date, num_days)  -- excludes weekends
+```
+
+---
+
+## Pivot Tables
+
+**When to use:** Summarizing large datasets by categories.
+
+**Setup:**
+1. Select data (including headers)
+2. Insert → Pivot Table
+3. Drag fields:
+   - Rows = categories to group by
+   - Columns = secondary grouping
+   - Values = what to calculate (Sum, Count, Average)
+
+**Refresh:** Right-click pivot → Refresh (data source changed)
+
+**Calculated fields:** Add custom calculations within pivot.
+

+
+## Common Errors & Fixes
+
+| Error | Cause | Fix |
+|-------|-------|-----|
+| #N/A | VLOOKUP can't find value | Check spelling, spaces, data type |
+| #REF! | Referenced cell deleted | Update formula references |
+| #VALUE! | Wrong data type | Check if text vs number |
+| #DIV/0! | Dividing by zero | Add IF to check denominator |
+| ##### | Column too narrow | Widen column |
+
+---
+
+## Data Cleaning
+
+**Remove duplicates:** Data → Remove Duplicates
+**Text to columns:** Data → Text to Columns (split by delimiter)
+**Find & Replace:** Ctrl+H, use wildcards (* for any characters)
+**Trim spaces:** `=TRIM(A1)` then paste values
