=ARRAYFORMULA( IMPORTXML($A1&$B1:$CZ1, "//suggestion/#data"))
so its do the rest of the job automatic I mean fetch data for A1and B1 in B2 and do A1 and C1 in C2 and A1 and D1 in D2, is it possible? I mean now I have to do manually enter formula in every column. hope you understand what I mean.

Answer 1

IMPORTXML is not supported in ARRAYFORMULA as you expect it. your options are:
paste in B2 and drag the formula to the right
=IMPORTXML($A1&B1, "//suggestion/#data")
paste in B2 the hardcoded formula for all columns:
={IMPORTXML(A1&B1, "//suggestion/#data"),
IMPORTXML(A1&C1, "//suggestion/#data"),
IMPORTXML(A1&D1, "//suggestion/#data")}

Answer 2

or scripted solution:
function onOpen() {
var sheet = SpreadsheetApp.getActiveSheet();
var length = sheet.getRange("B2:2").getValues().filter(String).length;
sheet.getRange("C3:3").clearContent();
sheet.getRange("C3:3" + length).setFormula(sheet.getRange("B3").getFormula());
sheet.getRange("C4:1000").clearContent();
}
where cell B2 is:
=ARRAYFORMULA(A1&B1:D1)
and cell B3 is:
=ARRAYFORMULA(IFERROR(IMPORTXML(B2:2, "//suggestion/#data")))
