vtiger 6.4 php tool to do data loads from excel

Dear Freelancers: DATA LOAD We have a 6.4 vTiger system, we need a SIMPLE php TOOL that will load excel files directly into 3 custom modules built with module builder. One module is a load of new entities with direct mapping of some 10 excel colums to vTiger fields. The other module will only UPDATE a single value, needs to match a unique field and update another based on the column name of the excel. The final module is a bit more complex, it will use a maping of a field on another CRM MODULE to fill a value, and the other 3-4 values are direct load. All loads need to report errors of rows that where not able to be loaded and for what reason (sql error is fine)... There's code that sends email if some value in one of the module is higher than a specified value, this code needs to still work in a way or another. OTHER DETAILS Enable history in 3 custom modules, as I can´t see the update history, ¿is it possible? There is no search by 1 custom module for some reason, ¿is it possible? Contact system ID to be forced to be equal to an ID in another field in the contact itself, then start contact ID numbering from the next apropiate one to keep numbering going forward from the last forced contact ID. ¿Is it possible?
