Thank you for the response. We are currently licensed for versions up to 3.10.0, is it possible to have a workaround for this problem until we upgrade to newer versions?

Hello,

we are generating a xlsx file with about 50k rows. We were using version 2.4.0. and it was taking around 5-6 seconds to complete. Recently, we've upgraded to 3.10.0 and now it's taking over 30 seconds, going into timeout.

Engine: handlebars
Recipe: xlsx

Template (with redacted data):

{{#xlsxReplace "xl/worksheets/sheet1.xml" "worksheet.sheetData[0].row[3].c[0]"}}
    <c t="inlineStr"><is><t> {{}}</t></is></c>
{{/xlsxReplace}}

{{xlsxRemove "xl/worksheets/sheet1.xml" "worksheet.sheetData[0].row" 6}}


{{#each DATA}}
{{#xlsxAdd "xl/worksheets/sheet1.xml" "worksheet.sheetData[0].row"}}

I need to do something similar, but I get an excel error when I try to insert the row.

I'm using <row r="">

For example using the screenshot @Genhan-Chen provided, if I add the row to position 19 or above(20, 21, 22 etc), it will work, but when I try to add row to anything below it, the excel file shows an error and there is no data. Doesn't matter what row, I can try to add row to position 4 or 5 for example which are empty, I still get the error, and excel file opens with no data in it.
