I have csv file in which suppose there are 3 spreadsheets sheet1,sheet2,sheet3. How can i import specific spreadsheet ,lets say sheet2 into neo4j?
A csv file does not have multiple sheets. I guess you're talking about an excel file.
You can either export each sheet into a separate excel file or use APOC's http://neo4j-contrib.github.io/neo4j-apoc-procedures/3.5/export-import/load-xls/
