NoEgress vs Excel, Power Query, ChatGPT and DuckDB

You already have tools for spreadsheets. Most of the time they’re enough, and this page says so. NoEgress is for one situation they handle badly: a file that is too big or messy for Excel, too confidential for ChatGPT, and you don’t write code.

The short version

Each tool wins somewhere. Here is where, side by side.

Tool	Better than NoEgress when…	NoEgress is better when…
Excel	You edit cells by hand, format a report, or the file is small.	The file has more than 1,048,576 rows, or you need to merge, compare or split files without VLOOKUPs and macros.
Power Query	You already know it and live in Excel on Windows.	You’re not on Excel for Windows, where Power Query is most complete, or you want repeatable steps without learning M.
ChatGPT and other AI chats	The data isn’t sensitive and you want open-ended help.	The file holds customers, salaries or patients and can’t leave your computer. The AI here runs on your machine.
DuckDB (command line)	You write SQL and scripts, and want automation.	You want the same engine with no install, no terminal and a table you can click.
A Python or R script	You program and need full control or a scheduled job.	You don’t program, or you need an answer in five minutes, not a script to maintain.

Excel: great until the file gets big or messy

Excel is the right tool for most small spreadsheets. It stops at 1,048,576 rows per sheet and won’t load the rest, and joining two files means VLOOKUPs that are slow to write and easy to break.

NoEgress opens files past that limit, removes duplicates, merges and compares files in a click, and exports back to Excel when you’re done.

Power Query: powerful, if you already speak it

Power Query records cleaning steps and re-runs them on next month’s file. If you already use it, keep using it.

NoEgress offers the same idea, saved steps you can re-run on a new file, in a browser tab on any operating system, with no M language to learn.

ChatGPT: the one most companies don’t allow for this

An AI chat is the easiest way to ask a file a question. It is also the one many companies forbid for customer, HR, financial and health data, because the file goes to someone else’s servers.

NoEgress runs a smaller AI model inside your browser, so you can ask in plain English and nothing is sent. It’s less clever than the big online models; the answers are computed by the database, so the numbers are exact.

DuckDB and scripts: the same engine, without the setup

NoEgress runs DuckDB underneath. If you’re comfortable in a terminal or in Python, you don’t need NoEgress: use DuckDB or pandas directly.

If you’re not, NoEgress gives you that engine with a table, a pivot and a chart on top, and no installation.

When you shouldn’t switch

If your files are small and not sensitive, Excel and ChatGPT are fine. If you write code, a script is more flexible. NoEgress earns its place when all three are true at once: the data is confidential, the file is big or messy, and you’d rather not program.

Frequently asked

Is NoEgress a replacement for Excel?

No. It’s for the jobs Excel is bad at: huge files, merging and comparing, and cleaning. Most people open the result in Excel afterwards.

How can the AI run without sending my data?

The model is downloaded to your browser once and runs on your own graphics chip through WebGPU. Your file is read on your computer and never uploaded, which you can check in your browser’s network panel.
