csvizsgálattal

A csvizsgálattal, or CSV investigation, refers to the process of examining data stored in Comma Separated Values (CSV) files. CSV files are a common format for storing tabular data, where each line represents a row and values within a row are separated by commas. A CSV investigation might be undertaken for various reasons, including data quality assessment, anomaly detection, forensic analysis, or understanding the contents of a dataset.

The initial steps in a CSV investigation often involve opening the file and inspecting its structure. This includes understanding the number of columns, the data types of each column (e.g., numerical, textual, date), and identifying any potential delimiters other than commas, such as semicolons or tabs, which may require specific handling. Tools commonly used for CSV investigations range from simple text editors for small files to specialized data analysis software like Python with libraries such as Pandas, R, or even spreadsheet applications like Microsoft Excel or Google Sheets for more complex tasks.

During the investigation, analysts look for inconsistencies, errors, or unusual patterns. This could involve checking for missing values, duplicate entries, out-of-range numerical data, or unexpected text formats. The objective is to ensure the data is accurate, complete, and suitable for its intended purpose. Depending on the context, a CSV investigation might also involve comparing different CSV files, tracking changes over time, or extracting specific subsets of data for further analysis. The outcome of a CSV investigation typically leads to data cleaning, validation reports, or insights into the dataset's characteristics.
