CELL function looks interesting but beware: language nightmares coming up…

Posted by jpluimers on 2026/03/26

A while ago I bumped into a very promising [Wayback/Archive] CELL function – Microsoft Support which exposes all sorts of interesting information on an Excel WorkSheet cell including address and filename.

But then this “disclaimer” threw me off:

Note: Formulas that use CELL have language-specific argument values and will return errors if calculated using a different language version of Excel. For example, if you create a formula containing CELL while using the Czech version of Excel, that formula will return an error if the workbook is opened using the French version.  If it is important for others to open your workbook using different language versions of Excel, consider either using alternative functions or allowing others to save local copies in which they revise the CELL arguments to match their language.

It means the CELL function is only useful if the spreadsheet containing it will only ever be used in a single language: say goodbye to portability.

That’s a real bummer as it would have simplified formulas like =ADDRESS(ROW(E7), COLUMN(E7)) into =CELL("address", E7) both resulting $E$7.

The big problem is that “consider either using alternative functions” is hardly possible as many of the functions have no alternative, for instance using the CELL function is the only way to get the name of the current worksheet (prepended by the filename) as =CELL("filename") returns Macintosh HD:Users:jeroenp:Downloads:[Workbook1.xlsx]Sheet1.

Note however:

Filename (including full path) of the file that contains reference, as text. Returns empty text (“”) if the worksheet that contains reference has not yet been saved.

The basic syntax of it is CELL(info_type, [reference]), where info_type and some of the return values being language dependent:

It might be time for me to upgrade to a newer Excel version because of some new notation and functions like TAKE and TRIMRANGE, or does it?

Posted by jpluimers on 2026/03/23

Over the last decades, I hardly needed to upgrade Excel. For a very long time I stayed at Excel 2003, as the ribbon interface introduced with Office 2007 (version 12) was horrible (it still is, especially since 19:10 monitors are gone and the ribbon takes too much vertical screen estate).

After that, I needed newer features so I upgraded to Excel 2013 (version 15) mainly because it ditched Multiple-document interface (MDI) and I like SDI over MDI a lot, and Office 2013 was largely compatible with Office for Mac 2011 (version 14).

Mostly recovered from my cancer treatments, I noticed that MacOS ditched 32-bit support in MacOS 11 Big Sur, which meant I could not use Office 2011 any more (it was 32-bit x86 only) so in 2022 I upgraded all my office installations to Office 2021 (up in the version 16.* range as starting with Office 2016 the major version number stayed 16.minor).

I might actually upgrade to Office 2024 (version 16.many) soon despite the major version 16, finally Excel has started sped up new development of new functions and features, of which the ones below are very interesting: they will make my largest spreadsheets a lot simpler and therefore easier to maintain:

Excel: sorting an array on 3 different columns using functions

Posted by jpluimers on 2025/09/09

Given Excel is the most popular functional language (see the video under my post “Everybody should have an obsession with Lisp-like language at least once in their life” @KevlinHenney), this post is on sorting with Excel functions.

I had an array in Excel starting at row 2 (to exclude the headings) where I had to sort on 3 different columns: C, A, B (or numerically 3, 1, 2) so [Wayback/Archive] sorting – How to multi level sort an array in excel, using formulas? I am aware about the way, using SORT button on DATA tab – Stack Overflow (thanks [Wayback/Archive] Armaan Gohil and [Wayback/Archive] Jos Woolley) didn’t fully apply but did put me on the right track as I wasn’t aware that the SORT function allows to specify multiple columns using an embedded array argument.

The functions that worked:

Office suites trick I was unaware off: you can use images as background of shapes, then distort by moving the corner points

Posted by jpluimers on 2025/05/26

The below example is in Excel, but it holds for many other drawing tools in other office suites as well (like the ones in OpenOffice and successors like LibreOffice, Apple Pages in iWork, and others from the list of office suites):

  1. Insert a shape
  2. Move the corners so it covers the area you want a screenshot in
  3. Modify the shape background to contain the screenshot as background

(you can exchange steps 2 and 3 if you wish, and even go for more complex shapes – including ones where you can add corner points – to better fit the area where you want the distorted screenshot to appear).

Example in (typo was indeed in the tweet) [Wayback/Archive] Excel Dictionary on X: “Are you ready for this Excel tip? Get ready to learn how to easily scew images. 🤯”: Read the rest of this entry »

Markdown has been the Internet’s lingua franca for documentation. Microsoft finally the documentation format with markitdown: Python tool for converting files and office documents to Markdown.

Posted by jpluimers on 2024/12/17

Finally an easier way to convert Office documents (and other formats) to markdown: [Wayback/Archive] GitHub – microsoft/markitdown: Python tool for converting files and office documents to Markdown. (after Google added a Markdown export feature to Google Docs about half a year ago, and basic Markdown formatting about 2 years ago – see below):

There are quite a few dependencies in [Wayback/Archive] markitdown/pyproject.toml at main · microsoft/markitdown · GitHub, so be prepared for that.

Supported formats (added links for clarity):

The MarkItDown library is a utility tool for converting various files to Markdown (e.g., for indexing, text analysis, etc.)
It presently supports:
  • PDF (.pdf)
  • PowerPoint (.pptx)
  • Word (.docx)
  • Excel (.xlsx)
  • Images (EXIF metadata, and OCR)
  • Audio (EXIF metadata, and speech transcription)
  • HTML (special handling of Wikipedia, etc.)
  • Various other text-based formats (csv, json, xml, etc.)

Google was first though:

  1. [Wayback/Archive] Google Workspace Updates: Compose with Markdown in Google Docs on web
  2. [Wayback/Archive] Google Workspace Updates: Import and export Markdown in Google Docs

There is speculation on why Microsoft introduced it just now ranging from “they need it for AI training” to “just late to the game”. I’m with the latter. Apple is even later, so if you want to convert Apple Notes to markdown, then you can use [Wayback/Archive] Import from Apple Notes – Obsidian Help.

Via various sources, including:

Belastingaangifte 2023 met Excel gratis downloaden | Computer Idee

Posted by jpluimers on 2024/08/27

Dit jaar was ik er een paar dagen eerder bij dan vorig jaar: meer rust in mijn hoofd na de verhuizing en een betere planning gemaakt rondom de paardrijvakantie van mijn verstandelijk beperkte broer (waar we altijd zorgen daar in de buurt te zijn zodat we indien nodig snel ter plaatse kunnen handelen).

Waarom is deze blog post zo laat?

Het laat heeft er vooral mee te maken dat deze Excel sheet meestal nog een aantal wijzigingen krijgt na de normale deadline van 1 mei. Dus ik begin pas met downloaden de maand voor de echt harde deadline van 1 september.

Waarom dan toch nu de post?

Eigenlijk is dat heel simpel: vooral zodat je kunt zien hoe je aan deze informatie komt ook al wijzigen de locaties: waar vorig jaar het Excel-bestand voor de belastingaangifte nog bij Google stond, staat het deze keer bij WeTransfer.

Dit jaar zijn de linkjes her en der dus behoorlijk anders: meer dan een simpele vervanging van 2022 door 2023 in de start-link van de eerste Google Search onderaan mijn blog-post.

Let ook op (dit vergat ik vorig jaar te vermelden): dit Excel bestand werkt bij mij niet op Office voor MacOS.

Omdat Computer Idee meestal geen jaartallen in de titels van hun artikelen gebruikt, moet je handmatig de zoekresultaten van Google Search door om te zien welke relevant voor aangifte over afgelopen jaar (in dit geval 2023) is/zijn. Vandaar dat ik hieronder op een aantal plekken jaartellen heb toegevoegd:

GitHub – dabochen/spreadsheet-is-all-you-need: A nanoGPT pipeline packed in a spreadsheet

Posted by jpluimers on 2024/06/12

A great visualisation that LLM are basically a bunch of numbers: [Wayback/Archive] GitHub – dabochen/spreadsheet-is-all-you-need: A nanoGPT pipeline packed in a spreadsheet.

It also shows you that Excel is an excellent tool for working with numbers and formulas on a larger scale.

It is a nanoGPT designed by @karpathy with about 85000 parameters, small enough to be packed into a spreadsheet file.
