AppScript to strikethrough partial text on match - google-apps-script

Question

I'm looking to get some help with Google Docs and Scripts. I have a workflow list that shows names of employees assigned to a task. There is also another field that indicates employees off of the day. I would like a script that can be run that would strikethrough the names of the individuals identified as off for the day. There could be multiple individuals off, so it would need to include a series of cells to reference. Results to look something like this.
[Requested outcome1
The problem I am running into is I cannot successfully find any code for even a starting point. I have seen pieces here and there, but nothing that is complete enough for me to even determine a starting point. I'm reasonably technical, but am not familiar with script writing. I have been unable to find a decent writeup on something like this so am requesting assistance if possible. Thank you!
Here is the code attempted where I am getting illegal argument on Line 27 currently. I will have it linked to a button. The individual in charge of updating the sheet daily will make all the daily changes, then once done click to button to clear any strikethrough and initiate based on new names input, if there are any.
Sample sheet link here.

var spreadsheet = SpreadsheetApp.getActive();
spreadsheet.getRange('B:B').activate();
spreadsheet.getActiveRangeList().setFontLine(null);
const sheetName = "Sheet1"; // Please set the sheet name.
const sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(sheetName);
const range = sheet.getRange('B2:B')
const textsForStrikethrough = sheet.getRange("A15:A20").getValues().flat(); // Added
const modify = range.getValues().reduce((ar, e, r) => {
e.forEach((f, c) => {
textsForStrikethrough.forEach(g => {
const idx = f.indexOf(g);
if (idx > -1) ar.push({start: idx, end: idx + g.length, row: r, col: c});
});
});
return ar;
}, []);
const textStyle = SpreadsheetApp.newTextStyle().setStrikethrough(true).build();
const richTextValues = range.getRichTextValues();
modify.forEach(({start, end, row, col}) => richTextValues[row][col] = richTextValues[row][col].copy().setTextStyle(start, end, textStyle).build());
range.setRichTextValues(richTextValues);
}

Answer 1

I believe your goal as follows.
You want to reflect the strikethrough to the partial text in a cell using Google Apps Script as follows. (The sample image is from your question.)
In this case, I would like to propose to use RichTextValueBuilder. The sample script is as follows.
Sample script:
function myFunction() {
const textsForStrikethrough = ["John"]; // Please set the texts you want to reflect the strikethrough.
const sheetName = "Sheet1"; // Please set the sheet name.
const sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(sheetName);
const range = sheet.getDataRange();
const modify = range.getValues().reduce((ar, e, r) => {
e.forEach((f, c) => {
textsForStrikethrough.forEach(g => {
const idx = f.indexOf(g);
if (idx > -1) ar.push({start: idx, end: idx + g.length, row: r, col: c});
});
});
return ar;
}, []);
const textStyle = SpreadsheetApp.newTextStyle().setStrikethrough(true).build();
const richTextValues = range.getRichTextValues();
modify.forEach(({start, end, row, col}) => richTextValues[row][col] = richTextValues[row][col].copy().setTextStyle(start, end, textStyle).build());
range.setRichTextValues(richTextValues);
}
Result:
When above script is run, the following results are obtained.
Input situation:
This is the sample input situation before the script is run.
Output situation 1:
In this case, const textsForStrikethrough = ["John"]; is used for the input situation.
Output situation 2:
In this case, const textsForStrikethrough = ["John", "Amy"]; is used for the input situation.
Note:
In this sample script, all values are retrieved from the sheet and search the texts and reflect the strikethrough. So when you want to use this script to the specific range, please modify const range = sheet.getDataRange(); for your situation.
For example, from your sample image, when you want to use this script to the column "B", please modify it to const range = sheet.getRange("B1:B" + sheet.getLastRow());.

About your following 2nd question,
This is perfect! Only other request I have, is how would we modify it to where it is referencing a series of other cells to lookup the names? The list of names changes daily, so looking to have all inputs be able to update by a simple change of the names on the sheet rather than modifying the code. So say the names could be input in cell A10:A15. Pulling that list of names and updating the "textsForStrikethrough" logic.
in this case, I think that at first, how about retrieving the values of cells "A10:A15", and use them as textsForStrikethrough?
Sample script 2:
function myFunction2() {
// const textsForStrikethrough = ["John"]; // Please set the texts you want to reflect the strikethrough.
const sheetName = "Sheet1"; // Please set the sheet name.
const sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(sheetName);
const range = sheet.getDataRange();
const textsForStrikethrough = sheet.getRange("A10:A15").getValues().flat(); // Added
const modify = range.getValues().reduce((ar, e, r) => {
e.forEach((f, c) => {
textsForStrikethrough.forEach(g => {
const idx = f.indexOf(g);
if (idx > -1) ar.push({start: idx, end: idx + g.length, row: r, col: c});
});
});
return ar;
}, []);
const textStyle = SpreadsheetApp.newTextStyle().setStrikethrough(true).build();
const richTextValues = range.getRichTextValues();
modify.forEach(({start, end, row, col}) => richTextValues[row][col] = richTextValues[row][col].copy().setTextStyle(start, end, textStyle).build());
range.setRichTextValues(richTextValues);
}
In this script, the values of cells "A10:A15" in the sheet of sheetName are used as textsForStrikethrough.
Note:
Unfortunately, I cannot understand about your actual situation. So when above script cannot be used for your actual situation, can you provide your sample Spreadsheet for replicating the issue? By this, I would like to confirm it.
