Csvjson helps you quickly convert popular data formats to the format you need. Data pasted and converted remains local on your computer.
CSV or Comma Separated Values is widely used for tabular data and often associated to spreadsheet applications like Excel.
Many data reporting tools output to CSV format.
JSON stands for JavaScript Object Notation and has become the defacto computer format readable by humans to store structured data.
From APIs to configuration files, JSON is now everywhere.
SQL stands for Structured Query Language and is the standard language for relational database management systems.
SQL is one of the most-used languages in the tech industry.
As a developer, format conversion is something we sometimes have to do. We often look online for solutions and tools finding they only cover partly our needs. Flatfile is proud to offer csvjson, a do-it-yourself csv converter to the community for free. Its best feature? You can save your session for later, and share it with a co-worker.
