It's not a user issue, it's a government incompetence issue. Who was the technical genius who thought 'right, we need to store thousands of lines of critical and important data, I know! Excel!'

Have you every worked in a large enterprise? I have personally tested an Excel based credit rating tool, to be rolled-out globally by a major financial institution. The fact that one should not do this, is by no means a reason not to do it.

Would be interested in hearing more about that Excel tool.

The way I heard it, it was an Excel problem: They had a CSV file that had more than 1 million lines, and Excel dropped the lines beyond 1 million. I can imagine an automated process that appended to the CSV and then Excel saving back to that same file with the lines stripped. I hope we can all agree that this is not the way Excel or any other software should behave, whether the user is incompetent or not.

If you read the article (perhaps its been updated?), they were using the old XLS format and they hit the limit at 64,000 lines PHE had set up an automatic process to pull this data together into Excel templates so that it could then be uploaded to a central system and made available to the NHS Test and Trace team as well as other government computer dashboards. The problem is that the PHE developers picked an old fil…

Like I said, that's the way I heard it, the way it was narrated to me.

The Guardian reported my version:

CSV would to me make more sense than an outdated binary format like XLS, but either story is plausible.

Excel is NOT a database. I don't understand the people who use it as such (and I've come across many who do). Then they're surprised when it all goes tits-up.

Excel may not be a database solution, but it is the most commonly used database solution.

This is indeed user incompetence, but so far every news source quoted the official PR and said it was an "Excel Problem". Microsoft PR was caught unprepared - I wonder how they'll re-spin it in the next few days (and for the first time that I can recall, a Microsoft product was wrongly blamed...) Pay attention, how every time there's a Windows virus or worm, it's a "Computer Virus", but in the (extremely rare) occasi…

The common case for stories like this is the answer is "nobody."

Time point 1: "We need a way to map the long-form epidemiology state. It's 2D data... Let's use Excel." "Will we hit limits?" "Pfft, no. Not unless we end up needing to track tens of thousands of patients, and that's not practical; we don't have enough people to do that tracking in the whole NHS."

Time point 2: "This pandemic is an URGENT problem. We need to hire more people than ever before to do tracing. And be sure to keep the epidemeology state mapper updated so it can drive the summary dashboards!"

I think you'd be shocked by how many of our financial and social institutions rely on emailing Excel spreadsheets to one another.

Don't forget healthcare! Excel and CSV for tons of data exchange.

We did a bit of work for laboratories this year and csv is not an uncommon exchange format between labs. In general almost all exchange formats are text based, with labs saying they will upgrade to „modern xml formats“ at some point in the future. So seen in this context a csv or an excel file doesn‘t really surprise me and should probably also be seen in this context.

> exchange formats are text based, with labs saying they will upgrade to „modern xml formats“ Worth noting that XML is also a text format. SGML even can treat CSVs as markup. There's nothing wrong with CSVs/TSVs anyway - it's a concise tabular format using only minimal special coding for a record and a field separator, as envisioned by ASCII and EDIFACT. The problem seems more like that there was no error checking in…

..this right here. No error checking, inadequate testing, no reconciliation process.

Excel is used extensively in many industries. Any file could be cut off in processing by any number of reasons, one off errors for e.g.

So the solution is to "fix" the process by using the existing broken process and smaller files....
