XLSX TO CSV GUIDE

A practical guide to XLSX to CSV conversion

XLSX is the modern Microsoft Excel workbook format, while CSV is plain-text tabular data separated into rows and columns. Converting between them can make the content easier to open, share or continue working with in the software used by your recipient.

Practical tip: Keep the original XLSX file until you have opened and checked the complete CSV result.
01

Why convert XLSX to CSV?

A CSV result is useful for moving structured data between spreadsheets, databases and other tools. Conversion creates a separate file, so keep the original XLSX when you may need its native features later.

02

Prepare your XLSX file

Check formulas, dates, merged cells, charts and print areas. Remove anything that should not appear in the finished file and use the clearest source available.

03

Check the CSV result

Check columns, dates, leading zeros and special characters. Pay particular attention to text, dimensions, colours, page order and any elements that are important to the document.
