Here an example that you can modify.

Code: Select all | Expand

#include "fivewin.ch"
Function Main()    //CsvToArrToDbf()    
  Local aArray := {}, aData := {}, aStruct := {}
  Local cTxtFile := MemoRead(".\CsvDbf.csv")    //your csv
  local nLines   := MlCount(cTxtFile)
  LOCAL n, aCols, aTypes, cSep := ",", nIniDataRow := 1, n2

  //Tipos al que serán convertidos (todos traen "C" por ser archivo de texto)
  aTypes := {"C","C","N","N","C","C"}

 //Si la primera linea contiene los headers
  aCols := HB_ATokens( Trim(Memoline(cTxtFile, 254, 1 )), cSep )
  nIniDataRow := 2  //Lin en que comienzan los datos

  For n := 1 to len(aCols)
     aadd( aStruct, { aCols[n], aTypes[n], 20, 0 } )
  Next
  DBCREATE( ".\CSVDBF", aStruct )
  DbUseArea(.t.,,".\CSVDBF", "CSVDBF", .f.)
  DbSelectArea("CSVDBF")

  FOR n := nIniDataRow TO nLines
     aArray := HB_ATokens( Trim(Memoline(cTxtFile, 254, n )), cSep ) 
     if !Empty(aArray)
        AEval( aArray, {|a,n| aArray[n] := ConvertType(aArray[n], aTypes[n]) } )
        DbAppend()
        For n2 := 1 to len(aArray) 
           FieldPut( n2, aArray[n2] )
        Next
     endif
  NEXT

  XBROWSER "CSVDBF"
  CSVDBF->(dbcloseArea())
  FERASE(".\CSVDBF.DBF")

Return nil

APPEND FROM <sourcefile> DELIMITED WITH ","

You still need to deal with removing the first row of the csv which has the field names, which is simple enough.

this function run ok onlyu when I found a csv have logic fields the function go out at line 16
a question ...

//Tipos al que serán convertidos (todos traen "C" por ser archivo de texto)
aTypes := {"C","C","N","N","C","C"}

I must set the field type ?

You can use field types, if you want it.
In the following example all fields are character type

#include "fivewin.ch"

  Local aArray := {}, aData := {}, aStruct := {}
  Local cTxtFile := MemoRead(".\CsvDbf.csv")
  local nLines   := MlCount(cTxtFile)
  LOCAL n, aCols,  cSep := ",", nIniDataRow := 1

  aCols := HB_ATokens( Trim(Memoline(cTxtFile, 254, 1 )), cSep )
  nIniDataRow := 2

  For n := 1 to len(aCols)
     aadd( aStruct, { aCols[n], "C", 20, 0 } )
  Next
  DBCREATE( ".\CSVDBF", aStruct )
  DbUseArea(.t.,,".\CSVDBF", "CSVDBF", .f.)
  DbSelectArea("CSVDBF")
  
  FOR n := nIniDataRow TO nLines
     aArray := HB_ATokens( Trim(Memoline(cTxtFile, 254, n )), cSep ) 
     if !Empty(aArray)
        DBAppend()            
        AEval( aArray, {|a,n| FieldPut(n, aArray[n]) } )
     endif
  NEXT
