Modify the PHP app to place a "=" in front of each number you want to
keep as a string. Simple example is ="123" Expanded example below.

They don't appear as a date when tested here. Keep reading.

The above is not proper CSV format. Modify your PHP program to
produce output that has each value within double quotes and each of
these quoted values separated by commas... like the following.

"Item","Name","Price","Amount","Total"
"123","Test","5.2","1","5.2"
"124","Test2","1.2","2","2.4"
"Total","","","","=sum(e2:e3)"

Read CSV spec if you have to deal with commas and/or quotes in your
actual data. And don't expect Excel to be fully cooperative. If
something doesn't work, you may need to Google for solutions specific
to Excel.

Your unaltered sample file (with preceding > removed) resulted in a
4-line spreadsheet with all data for that line in column A of the
resulting Excel... as string data.

My revision (above) to your output results in items in separate
columns, but "Item" data that you want as a string is numeric.

The following is the output you want from your PHP program in order
for the "Item" data to appear as strings when imported into Excel. You
just stick an "=" in front of the quoted value to make Excel see it as
a string. If you wanted the price as a string then an example of what
should be between the commas would be ="5.2"

="Item","Name","Price","Amount","Total"
="123","Test","5.2","1","5.2"
="124","Test2","1.2","2","2.4"
"Total","","","","=sum(e2:e3)"

> I'd like to have 123 and 124 as strings, and eg 5.2 as a float.

My little rev (immediately above) to your output displays 5.2 as a
float, not a string.

> Can I format it better than this?

Try my examples and I think all your problems will go away.
