CSV file guide

Rows and columns in a text file

What it stores

CSV stores rows of delimited text. Quoted fields can contain commas and line breaks; encoding and header conventions vary between applications.

When to choose it

Use CSV for exchanging a simple table. Select the correct character encoding and inspect the column names before converting to JSON.

What to check before converting

Leading zeros, dates and long identifiers can be changed by spreadsheet software when opened. Coverton neutralizes formula-like cells in supported table exports; encoding-only conversion preserves the original text.
