$750-1500 USD

Paid on delivery
We want to develop a client-side data packaging tool that converts information stored in various file types (such as .csv, .xls, .xlsx, .mdb, .accdb, etc.) and structures (wide, long, dyadic, etc.) into a standardized .json format, to be uploaded into our data analytics system. The data-packaging tool will interface with the the existing system by way of a client-side API. This packaging tool will act in place of the current command based tool for uploading data into our data analytics system. The product will need to include standard user interface tools used to facilitate data locating and selection. It also needs to be robust enough to identify different variants of standard data fields and records, including non-standard characters, and reformat and package them into the final .json format that the system recognizes. We are looking for developers with expertise in web programmatic Interface (API) and RESTful application design, who are capable of designing user interface with little support from the primary developer who has developed the main data analytics system. The desired candidate should have previous experience working and successfully completing projects based on Web Programmatic Interface (API) in RESTful platforms. This project has the possibility of becoming a longer-term arrangement for the development of additional auxiliary components for the Data-Gator project. Please refer to the project proposal and its supporting document for further information. Project Follow up team.

Dear Sir, Thank you for your invitation & interest in our Company. We have read your Project Description & understand the overall requirements of your project, as you have already explained all the features very well. However, our major concern is that your budget of US $1,500 is low as compare to the working Man-Hours involved to deliver it, as you know that we have to estimate the project based on the overall features. So, do you think that you can be flexible in it? If not, then no problem and we totally understand. Our current bid is just a placeholder since Freelancer requires it but once you respond us, we can then provide you our estimate. Look forward to hearing from you and talking to you further thru' Freelancer private message board. Regards, YK LEADconcept

Hi. This is an interesting and challenging project. basically you want to to standardise any input format to some other output .json one which will be used later for any kind of statistic? I didn't read all the attached file till the end, but have few questions: 1. Basically a web UI is needed where users can upload any type of files and it should allow some kind of mapping from user's format to new format? 2. Does if needs to automagically detect the file type? Or user have to manually specify it? 3. About the API, RESTfull one? So, we will interact with a resfull api or willl build one? This are just few questions, I may update the list after reading the attachments. Thx. Hope we will collaborate.
