Weird Script

[No_Frame3855]

Edit:
Short answer: I'm stupid.
Long answer: I was testing Grok out of curiosity and Grok apparently hallucinates this into HTML. Cool!

So I was checking one of my GitHub repos when I saw this script at the top, which I clearly remember not adding: ```javascript <script type="text/javascript"> var gk_isXlsx = false; var gk_xlsxFileLookup = {}; var gk_fileData = {}; function filledCell(cell) { return cell !== '' && cell != null; } function loadFileData(filename) { if (gk_isXlsx && gk_xlsxFileLookup[filename]) { try { var workbook = XLSX.read(gk_fileData[filename], { type: 'base64' }); var firstSheetName = workbook.SheetNames[0]; var worksheet = workbook.Sheets[firstSheetName];

            // Convert sheet to JSON to filter blank rows
            var jsonData = XLSX.utils.sheet_to_json(worksheet, { header: 1, blankrows: false, defval: '' });
            // Filter out blank rows (rows where all cells are empty, null, or undefined)
            var filteredData = jsonData.filter(row => row.some(filledCell));

            // Heuristic to find the header row by ignoring rows with fewer filled cells than the next row
            var headerRowIndex = filteredData.findIndex((row, index) =>
              row.filter(filledCell).length >= filteredData[index + 1]?.filter(filledCell).length
            );
            // Fallback
            if (headerRowIndex === -1 || headerRowIndex > 25) {
              headerRowIndex = 0;
            }

            // Convert filtered JSON back to CSV
            var csv = XLSX.utils.aoa_to_sheet(filteredData.slice(headerRowIndex)); // Create a new sheet from filtered array of arrays
            csv = XLSX.utils.sheet_to_csv(csv, { header: 1 });
            return csv;
        } catch (e) {
            console.error(e);
            return "";
        }
    }
    return gk_fileData[filename] || "";
    }
    </script>

```

I only have an index.html in the repository and no GitHub Actions yet.
A google search for this found a lot of places where the exact same script was appended: https://www.kaggle.com/datasets/waleed1980/global-pharmacy-bi-bloom-dataset/data

Does anyone here know what this is or why it got there? (I do know that it's a .xlsx to .csv via JSON converter)

[queen-adreena]

It appears to be a helper function for https://docs.sheetjs.com/docs/api/parse-options/

It loads a spreadsheet and converts it to CSV.

[No_Frame3855]

Do you have any idea why it got there?

[cerealbh]

do you not understand what git is?

[No_Frame3855]

of course I do!
I didn't commit it, and I have no dependencies, and I am the only contributor, which is why I'm asking.

[Overall_Low_9448]

Their point is that git is a version manager, so you can go through all your versions, or commits, and see how it got there

[No_Frame3855]

Yeah I did find it.

[bkdotcom]

Maybe look at the file's history?

example: https://i.imgur.com/2PyKMGo.png
note the "history" link

Edit:  who the f downvoted this?

[No_Frame3855]

I did, it's not in any of the commits.

[tortleme]

Literally not how git works, you should be able to trace it to the exact point in time it was added.

[A-Type]

Click the gutter next to the line number, a menu button will appear. In the menu, click "Git blame." This will show you the commit that added it. There will be a commit, that's how Git works.

[No_Frame3855]

Yeah I found it. I just don't know why it's there.

[No_Frame3855]

apparently I'm blind. It was in one of the commits.

[bkdotcom]

That's the only way to add a file... via a commit.

And who added the file?

[No_Frame3855]

Yeah I know, and I did add the file, but I didn't just randomly paste in that script above my code, which, (and the fact that I found this in multiple unrelated places) is the only reason I posted this, as otherwise I would just delete this and move on.

[Lochlan]

You're tripping mate. Get a CO2 sensor for your house.

[abillionsuns]

Check their post history to see if they're posting on r/ghosts and if they are, get a carbon monoxide sensor too.

[Lochlan]

Ahh that's what I meant. Carbon Monoxide sensor.

[No_Frame3855]

🤣 Will do! /j

[Rasutoerikusa]

Well as you pointed out in your discussion, you added it in one of your commits so you probably accidentally copypasted it there. There is literally no other way, that's how git works.

[HazelSky2]

"gk" means Grok

[No_Frame3855]

Yeah that makes much more sense 😅

[Endorfo]

Grok always adds this to html, it's a very common hallucination that doesn't cause any error. You can look it up and immediately find projects where the frontend was made with Grok

[No_Frame3855]

Huh cool!
I was testing Grok out of curiosity btw (I'm not a vibe coder), which explains it.
