Excel Formulas & Functions: The Complete Guide
Excel skill gaps cost small businesses more than they realize. A broken VLOOKUP or a manually rebuilt pivot table is rarely dramatic, but it eats hours every week, quietly, across every person who touches a spreadsheet.
This page organizes our full library of Excel and Google Sheets tutorials by skill area, from absolute beginner formulas to CFO-level financial functions, so you can find the exact guide you need instead of searching one article at a time.
Quick Answer
The core Excel skill areas are lookup functions (VLOOKUP, INDEX/MATCH), logical functions (IF, AND, OR), data organization (sorting, filtering, pivot tables), formatting (conditional formatting, data validation), and financial functions used for business calculations. Most people only need a handful of functions well; this guide is organized so you can go straight to the ones relevant to your work.
Key Takeaways
- VLOOKUP and INDEX/MATCH solve the same core problem, looking up a value in a table, but INDEX/MATCH is more flexible for larger datasets.
- Pivot tables are the fastest way to summarize large datasets without writing formulas.
- Conditional formatting and data validation prevent errors before they happen, rather than catching them after.
- Most Excel slowdowns come from formatting bloat and volatile formulas, not file size.
- A small set of financial functions covers most day-to-day business calculations.

| Skill Area | What It Solves | Best For |
|---|---|---|
| Lookup Functions (VLOOKUP, INDEX/MATCH) | Finding and pulling matching data across tables | Anyone merging data from multiple sheets |
| Logical Functions (IF, AND, OR) | Returning different results based on conditions | Building rules-based calculations |
| Pivot Tables | Summarizing large datasets without formulas | Reporting and dashboards |
| Conditional Formatting | Visually flagging data based on rules | Highlighting outliers and exceptions |
| Financial Functions | Loan, depreciation, and investment calculations | Finance and executive reporting |
| Macros & Power Query | Automating repetitive tasks | High-volume, recurring spreadsheet work |
Getting Started
If you are new to Excel or Google Sheets entirely, start with the fundamentals: navigating the interface, entering data correctly, and understanding how formulas reference cells. Getting these basics solid prevents most of the errors that show up later in more complex formulas.
Lookup & Logical Functions
VLOOKUP and INDEX/MATCH are the two functions that unlock the most value for the least effort. If you regularly copy-paste data between sheets to match records, one of these functions almost certainly replaces that process. IF, AND, and OR statements layer on top, letting you build rules that return different results depending on the data.
Lookup, Logic & Data Functions
The functions that do the most work in day-to-day spreadsheets.
Formatting, Charts & Dashboards
Making data readable and presentable.
Sorting, Filtering & Data Cleanup
Organizing and cleaning data before you analyze it.

When spreadsheets stop being enough
Excel and Google Sheets handle a lot, but there is a point where manually maintained formulas become the bottleneck: time tracking, payroll, and reporting that has to stay accurate as a team grows. Updoot picks up where the spreadsheet stops scaling, with time tracking, payroll, and reporting that update automatically instead of needing a formula rebuilt every time something changes.
Frequently Asked Questions
VLOOKUP searches for a value in the leftmost column of a range and returns a value from a specified column to the right. INDEX/MATCH is more flexible: it can look left or right and does not break as easily when columns are inserted or reordered, which makes it the better choice for larger or frequently changing datasets.
No. Most day-to-day Excel work is handled well with core formulas, pivot tables, and formatting. Macros and VBA become valuable once you are repeating the exact same multi-step process regularly and want to automate it, but they are not required for typical business use.
Slowdowns usually come from formatting bloat (formatting applied to entire rows or columns instead of just the used range), volatile formulas that recalculate constantly, and excessive conditional formatting rules, rather than from data volume alone.
A pivot table is almost always faster and more flexible than building summary formulas manually. It lets you group, filter, and total data interactively without writing a single formula.
Most common formulas work identically or nearly identically in both. Some advanced functions and features differ, and Google Sheets has a few functions Excel does not (and vice versa), but core functions like VLOOKUP, IF, and SUMIF behave the same way in both.
