CSV file format information

Full NameComma-separated Values
Mime Typetext/csv

A CSV (Comma-Separated Values) file is a simple and widely used data file format that stores tabular data, such as spreadsheet-like information, in plain text. Each line in the CSV file represents a single record, and each field within a record is separated by a delimiter, typically a comma, hence the name. However, other delimiters like semicolons or tabs can also be used. This straightforward structure makes CSV files easy to create, read, and parse by both humans and computer programs.

CSV files are commonly employed to exchange data between different applications and platforms because of their universality and compatibility. They are especially useful for databases, spreadsheets, and other data storage systems, as they provide a convenient way to organize structured information. Many spreadsheet software, like Microsoft Excel and Google Sheets, allow users to import and export data in CSV format.

Despite its simplicity, a CSV file can hold a vast amount of data, making it a versatile choice for various purposes. However, since CSV lacks data types and metadata definition, it's essential to ensure data integrity and consistency when using CSV files. Proper handling and validation are necessary to prevent errors or issues when processing the data contained within.

Repairing a CSV File

CSV File Header Data

CSV files contain a sequence of unique bytes at the beginning of the file. This header section is usually followed by the main CSV file section. Where the header block is present, our document repair tool will parse the header data to validate the file type and also provide additional metadata that describes key characteristics of the document uploaded.
