TSV to CSV

Converting a text file to CSV is one of the most common data tasks there is — and also one of the most misunderstood. The actual file format difference between TXT and CSV is smaller than most people think. Both are plain text. Both store data as characters. The difference is structure: a CSV file uses commas to separate values into columns and line breaks to separate rows, following a defined pattern that every spreadsheet, database, and analytics tool understands natively. A plain TXT file might have that same structure already — values separated by tabs, pipes, spaces, or commas — but saved with the wrong extension or without the standard delimiter that downstream tools expect. Converting it to CSV means reformatting the delimiter into standard comma separation and saving the result with a .csv extension so every tool opens it correctly. This guide covers every method: a free online converter for quick single-file conversions, Microsoft Excel's built-in import wizard for structured workflows, and Python for batch or automated processing. It also covers the most common problems — encoding errors, misaligned columns, and delimiter confusion and how to fix them.

Converting an Excel spreadsheet to CSV — or bringing a CSV file back into Excel — is one of the most common data tasks people run into. Whether you need to import data into a database, feed a file into an analytics tool, or share clean data with a developer, this guide covers every method, every problem, and every question you will run into.

Every developer who has pulled data from an API knows the moment: you have a clean JSON response, but your client, manager, or data team needs it in a spreadsheet — now. The question is not whether JSON to CSV conversion is possible. It is the method that is fastest, most reliable, and right for your specific situation.
