CSV Format Tips

CSV (Comma-Separated Values) is a simple format for representing tabular data:

  • Each line is a data record (row)
  • Fields are separated by commas (or other delimiters)
  • Fields with commas should be enclosed in double quotes
  • The first row often contains column headers
  • Double quotes within quoted fields should be escaped with another double quote
JSON Format Tips

JSON (JavaScript Object Notation) is a structured data format:

  • Data is represented as key-value pairs
  • Arrays are ordered collections of values
  • Objects are unordered collections of key-value pairs
  • Values can be strings, numbers, objects, arrays, booleans, or null
  • JSON is language-independent but uses JavaScript syntax
