Google Sheets API NodeJS - Update cell without changing format - node.js

Question

Have written NodeJS code to Insert a Row in a Google Sheet using the API and updating the row values.
I insert the row with inheritFromBefore: true, which is working fine (I tested it by commenting out the updateOption). But while updating the cell the original format is not getting preserved; rather it is changing to default blank format.
function getSheetRow(jobData) {
const jobID = jobData.getJobID();
const jobName = jobData.getJobName();
const company = jobData.getCompany();
const pmName = jobData.getPMName();
let rowData = [
{ userEnteredValue: { stringValue: jobID } },
{ userEnteredValue: { stringValue: jobName + " (" + company + ", " + pmName + ")" } }
];
return rowData;
}
async function googleSheetInsertRow(workbookID, sheetNum, insertRowIndex, jobData) {
let sheetIdMap = await googleSheetsGetSheetIDTitle(workbookID);
let rowData = getSheetRow(jobData);
return new Promise((resolve, reject) => {
const insertOption = {
insertDimension: {
range: {
sheetId: sheetNum,
dimension: 'ROWS',
startIndex: insertRowIndex,
endIndex: insertRowIndex + 1
},
inheritFromBefore: true
}
};
const updateOption = {
updateCells: {
rows: [{
values: rowData
}],
fields: '*',
start: {
sheetId: sheetNum,
rowIndex: insertRowIndex,
columnIndex: 0
}
}
};
getGSheetsAPI().spreadsheets.batchUpdate({
spreadsheetId: workbookID,
resource: {
requests: [
insertOption, updateOption
]
}
},
(er, re) => {
if (er) {
console.log(`Unable to insert new row into ${googleSheetName} : https://docs.google.com/spreadsheets/d/${workbookID}`);
return reject(er);
}
else {
console.log(`New row inserted into ${googleSheetName} : https://docs.google.com/spreadsheets/d/${workbookID}`);
return resolve();
}
}
);
});
}
[In the picture below] I have inserted a row in between Row 6 & 8. And Row 7 is inheriting the format from the row before, but while updating the cell value it is not getting preserved.
Looking for help. Thanks.

I think that in your issue, when userEnteredValue or userEnteredValue.stringValue is used to fields, the issue can be resolved. When you want to use the values except for stringValue, I would like to recommend to use userEnteredValue as the fields.
From:
const updateOption = {
updateCells: {
rows: [{
values: rowData
}],
fields: '*',
start: {
sheetId: sheetNum,
rowIndex: insertRowIndex,
columnIndex: 0
}
}
};
To:
const updateOption = {
updateCells: {
rows: [
{
values: rowData,
},
],
fields: "userEnteredValue", // <--- Modified
start: {
sheetId: sheetNum,
rowIndex: insertRowIndex,
columnIndex: 0,
},
},
};
