Windows 10: What is the best setup for large Excel files and having instructions formulas, lookups,...

Greg Easton1 · Feb 6, 2024

Currently running Windows Pro 10, version 22H2. Have the Intel W-2135 processor with 128GB of RAM. and a 64-bit operating system. When I do a Fuzzy look up with under 40,000 rows, current system works fine, takes less than 30 seconds. When I do a Fuzzy look up with 170,000+ rows, it take over 3 hours. Any insight/ help / suggestions would be greatly appreciated.

Formulas

is there a way to use LOOKUP (or any other formula) to add values from a large number of different

sheets in the same file?

"Worksheet names—In a cell in a worksheet, Excel Mobile accurately displays names that reference worksheets within the same workbook. It removes names that refer to other workbooks, arrays such as ={1;2;3;4}, array formulas, or intersection ranges
from the name list. When Excel Mobile removes a name from the list, it leaves the name in formulas and functions. This causes those formulas to be resolved as "#NAME?" Tabs that are hidden in the workbook are not hidden in Excel Mobile."

New way to debug formulas in Excel

Have you ever found yourself tangled in a web of complex Excel formulas, desperately trying to pinpoint the source of an error? Fret no more! The latest experiment from Excel Labs is a new formula debugger, available within the Advanced Formula Environment (AFE).

The AFE debugger Getting started The debugging capabilities are activated using the new button on the Grid page in AFE. When the button is activated the debugger will be visible in the same editing pane, and you are ready to go! Key features Here are some of the key features to look out for: - Live debugging The debugger updates as you type, making it quick to explore how different variations of a formula are evaluated.

Live debugging as you edit the formula - Evaluation steps Each evaluation step is shown, with highlights and underlines making it easy to see what changed at every step.

Evaluation steps show each change in the formula - Range preview View a preview of the grid when hovering over a reference. Previews show the surrounding context to make it easier to navigate.

Preview referenced grid ranges - LAMBDA debugging Debug LAMBDA formulas, such as SalesForBestCategory, shown below. Every function call is contained in an expandable card. This lets you dive into the particular functions you are interested in, to see how they evaluate.

Debug LAMBDA formulas Function support Not all functions are supported just yet. If a function or scenario is blocking your work, we would love to hear about it! In case you missed it: Sheet-defined functions Another experimental feature in the advanced formula environment is the ability to automatically convert a multi-cell calculation into a function, also known as sheet-defined functions. This capability has been part of AFE for a while, but in case you missed it – here is a brief overview. Often, we find ourselves spreading a complex calculation over many cells, like this one, that extracts an ID from a piece of text.

Multi-cell calculation for extracting an ID After writing the calculation we are either faced with many intermediate cells, or we must roll the formulas into a single mega-formula. With AFE and the “Add function from grid” feature, we can automatically convert these formulas into a tidy function using three simple steps:

First, select the range containing the formulas that will make up the function.

Then click the “Add function from grid” button and provide the references that will define the inputs and outputs. Sometimes, AFE can automatically detect the inputs and outputs based on the dependencies.

Finally, AFE will present you with the generated function that combines the formulas in the range. If you use labels adjacent to formulas, AFE can also use those to generate friendly parameter names, like Text or After.

Define a custom function from cells in the grid How to access The debugger will be pushed to Excel Labs automatically and there is no need to explicitly update the add-in. If you do not have Excel Labs, you can install the add-in from the Office store. Follow this link.
