how to get cpp boost ptree json array root json string

Why

because default cpp boost ptree json not support root array json format.
there is so many other json parse engine on internet.
buy i want to reused boost ptree.

my code:

ptree r, r0, p1, p2;
ptree p0, p, c1, c2;

c1.put("c1a", "a");
c1.put("c1b", "b");
c2.put("c2a", "a");
c2.put("c2b", "b");

p.push_back(std::make_pair("", c1));
p.push_back(std::make_pair("", c2));
p0.push_back(std::make_pair("", p));
std::string s;
std::stringstream ss;
write_json(ss, p0);
s = ss.str();

i want to get below string format:

[
   {...},
   {...}
  ]

but boost ptree generate string like this:

{
  "":[
   {...},
   {...}
  ]
}

How:
remove string above of '[' and after ']':

std::string getJArrayString(const ptree& p) {
ptree p0;
p0.push_back(std::make_pair("", p));

std::stringstream ss;
write_json(ss, p0);
std::string s = ss.str();

do {
auto b = s.find_first_of('[');
if (b == std::string::npos)
break;

auto e = s.find_last_of(']');
if (e == std::string::npos)
break;
s = s.substr(b, e + 1 - b);

return s;
} while (false);

return "[]";

}

and call this:

ptree r, r0, p1, p2;
ptree p0, p, c1, c2;

c1.put("c1a", "a");
c1.put("c1b", "b");
c2.put("c2a", "a");
c2.put("c2b", "b");

p.push_back(std::make_pair("", c1));
p.push_back(std::make_pair("", c2));
p0.push_back(std::make_pair("", p));
std::string s = getJArrayString(p0);

fixed error to get the value of VCTargetsPath:

How To change Vlookup Matching Value From Bottom To Top In Excel 2016?

What?
How To Vlookup Matching Value From Bottom To Top In Excel?

Why?
Because default excel vlookup function search direction is from top to down, i need from down to top in finance data analyse.

my want formula is:

=VLOOKUP(G28,G27:H2,2,FALSE) but excel change it to =VLOOKUP(G28,G2:H27,2,FALSE)

How:
I Find answer from here: https://www.extendoffice.com/documents/excel/3404-excel-vlookup-from-bottom.html

Last i get the right formula is:

=LOOKUP(2,1/($G$2:$G$27=G28),$H$2:$H$27)

FINAL:

By use current row variable optimized code is:

=LOOKUP(2,1/(INDIRECT(CONCAT("G2:G",VALUE(ROW()-1)))=INDIRECT(CONCAT("G",ROW()))),INDIRECT(CONCAT("H2:H",ROW()-1)))
