QR codes are no longer just black-and-white squares on restaurant tables. They are on business cards, wedding invitations, product packaging, social media profiles, event tickets, and storefront windows. Over 2.2 billion people scanned a QR code globally in 2026 — and that number is growing every year.

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.

Saving a Word document as a PDF is one of the most common things people do with Microsoft Word — and one of the most misunderstood. Some versions of Word call it "Save As." Others call it "Export." On Mac, it's buried under a different menu. On mobile, it works differently again.
