FAQ
Frequently asked questions
How do I convert XLSX to CSV?+
Upload your XLSX file (or drag it onto the box above), wait a few seconds while StandardsPDF converts it in your browser, then download the CSV. There is nothing to install and no account required.
Is converting XLSX to CSV free?+
Yes. XLSX to CSV conversion is free on the StandardsPDF free tier – no watermark, no signup, and no credit card. A Pro tier lifts the file-size and daily limits if you need more.
Will the CSV keep the quality of my XLSX?+
StandardsPDF aims for the highest fidelity the CSV format allows, so your spreadsheet comes through looking as close to the original as possible. Some format-specific details may adapt where CSV works differently to XLSX.
Are formulas kept when I convert XLSX to CSV?+
Cell values, rows and columns from your XLSX are always preserved. Live formulas carry into the CSV when it supports them, otherwise they become their calculated values.
What is the maximum XLSX file size I can convert to CSV?+
Up to 100 MB per XLSX on the free tier and 2 GB on Pro. If your XLSX is larger, split it first or upgrade for the higher limit.
Can I convert several XLSX files to CSV at once?+
Yes – add multiple XLSX files and StandardsPDF processes them as a batch, returning a CSV for each.
Can I convert XLSX to CSV on my phone?+
Yes – the XLSX to CSV converter is fully responsive and works in Safari, Chrome and other modern browsers on iOS, Android and iPadOS.
How long does a XLSX to CSV conversion take?+
Most XLSX files convert to CSV in a few seconds. Larger or higher-resolution files take a little longer, but there is never a queue on the free tier.
