everyone, I tried to convert my csv to json, using the code below:

f = open( 'D:\\ResumesClassification\\test2.csv', 'r' )
fieldnames =("id","basicinformation","workexperience","education","skill","publication","add tionalinformation","link","award","certification")
reader = csv.DictReader( f,fieldnames)
out = json.dumps( [ row for row in reader ] )
fo = open('D:\\ResumesClassification\\test2.json','w')
fo.write(out)
fo.close()
print out

And when I used mongoimport, it said json decoder out of sync - data changing underfoot, this is how my .json look like:

[{"publication": "Structural basis for modulation of a G-protein-coupled receptor by allosteric drugs Nature,http://www.nature.com/nature/journal/v503/n7475/full/nature12595.htmlOctober 13, 2013The design of G-protein-coupled receptor (GPCR) allosteric modulators, an active area of modern pharmaceutical research, has proved challenging because neither the binding modes nor the molecular mechanisms of such drugs are known1, 2. Here we determine binding sites, bound conformations and specific drugreceptor interactions for several allosteric modulators of the M2 muscarinic acetylcholine receptor (M2 receptor), a prototypical family A GPCR, using atomic-level simulations in which the modulators spontaneously associate with the receptor. Despite substantial structural diversity, all modulators form cation interactions with clusters of aromatic residues in the receptor extracellular vestibule, approximately 15 from the classical, orthosteric ligand-binding site. We validate the observed modulator binding modes through radioligand binding experiments on receptor mutants designed, on the basis of our simulations, either to increase or to decrease modulator affinity. Simulations also revealed mechanisms that contribute to positive and negative allosteric modulation of classical ligand binding, including coupled conformational changes of the two binding sites and electrostatic interactions between ligands in these sites. These observations enabled the design of chemical modifications that substantially alter a modulators allosteric effects. Our findings thus provide a structural basis for the rational design of allosteric modulators targeting muscarinic and possibly other GPCRs.High-resolution crystal structure of human protease-activated receptor 1http://www.nature.com/nature/journal/v492/n7429/full/nature11701.htmlDecember 9, 2012Protease-activated receptor 1 (PAR1) is the prototypical member of a family of G-protein-coupled receptors that mediate cellular responses to thrombin and related proteases. Thrombin irreversibly activates PAR1 by cleaving the amino-terminal exodomain of the receptor, which exposes a tethered peptide ligand that binds the heptahelical bundle of the receptor to affect G-protein activation. Here we report the 2.2--resolution crystal structure of human PAR1 bound to vorapaxar, a PAR1 antagonist. The structure reveals an unusual mode of drug binding that explains how a small molecule binds virtually irreversibly to inhibit receptor activation by the tethered ligand of PAR1. In contrast to deep, solvent-exposed binding pockets observed in other peptide-activated G-protein-coupled receptors, the vorapaxar-binding pocket is superficial but has little surface exposed to the aqueous solvent. Protease-activated receptors are important targets for drug development. The structure reported here will aid the development of improved PAR1 antagonists and the discovery of antagonists to other members of this receptor family.Structure and dynamics of the M3 muscarinic acetylcholine receptorhttp://www.nature.com/nature/journal/v482/n7386/full/nature10867.htmlFebruary 22, 2012Acetylcholine, the first neurotransmitter to be identified, exerts many of its physiological actions via activation of a family of G-protein-coupled receptors (GPCRs) known as muscarinic acetylcholine receptors (mAChRs). Although the five mAChR subtypes (M1-M5) share a high degree of sequence homology, they show pronounced differences in G-protein coupling preference and the physiological responses they mediate. Unfortunately, despite decades of effort, no therapeutic agents endowed with clear mAChR subtype selectivity have been developed to exploit these differences. We describe here the structure of the G(q/11)-coupled M3 mAChR ('M3 receptor', from rat) bound to the bronchodilator drug tiotropium and identify the binding mode for this clinically important drug. This structure, together with that of the G(i/o)-coupled M2 receptor, offers possibilities for the design of mAChR subtype-selective ligands. Importantly, the M3 receptor structure allows a structural comparison between two members of a mammalian GPCR subfamily displaying different G-protein coupling selectivities. Furthermore, molecular dynamics simulations suggest that tiotropium binds transiently to an allosteric site en route to the binding pocket of both receptors. These simulations offer a structural view of an allosteric binding mode for an orthosteric GPCR ligand and provide additional opportunities for the design of ligands with different affinities or binding kinetics for different mAChR subtypes. Our findings not only offer insights into the structure and function of one of the most important GPCR families, but may also facilitate the design of improved therapeutics targeting these critical receptors.", "certification": "", "basicinformation": "Hillary GreenData Scientist - KnewtonNew York, NY-Authorized to work in the US for any employer", "award": "", "link": "", "workexperience": "Data ScientistKnewton - New York, NYNovember 2014 to PresentData Scientist - Embedded in Direct to Institution Team Use Big Data to advise the Direct to Institution team on how students and teachers are using the product, how to improve analytics for teachers and students, and how changes to the product might affect current users Create informative, beautiful, and dynamic data visualizations that convey key information about large data sets (javascript, d3, matplotlib) Create tools for processing, labeling, and understanding large, messy datasets (python, pandas, numpy) Write blog posts that highlight data insights to a general audience (https://www.knewton.com/blog/adaptive-learning/how-instructors-use-adaptive-assignments-in-the-classroom/https://www.knewton.com/resources/blog/adaptive-learning/visualizing-personalized-learning/https://www.knewton.com/resources/blog/adaptive-learning/friday-effect-students-really-worse/https://www.knewton.com/resources/blog/adaptive-learning/school-holidays-affect-student-scores/) Leadership: occasionally lead team stand-ups and sprint planning; advise other data scientists on best practices; review data science codeData Scientist - Efficacy Research Lead internal efficacy research efforts, including designing observational studies, performing complex data analysis, writing technical papers, and presenting results to both internal and external audiences Advise partner companies on efficacy research strategies, including study design and methodology and data analysis strategies Use Big Data to demonstrate the impact of adaptive learning technology Report research findings to internal and external audiences via papers, presentations, and visualizations(https://www.knewton.com/resources/blog/adaptive-learning/adaptive-advantage-reducing-performance-gap/)Scientific AssociateD.E.

I wonder why you are using DictReader. instead you can do this:

  1. read csv file line by line
  2. split it by tab or comma.
  3. create json object add each element from splitted list to json object
  4. write json object to your json file

what's your interest
