FAQ
Frequently asked questions
How do I convert XLS to CSV?+
Upload your XLS 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 XLS to CSV free?+
Yes. XLS 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 XLS?+
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 XLS.
Are formulas kept when I convert XLS to CSV?+
Cell values, rows and columns from your XLS are always preserved. Live formulas carry into the CSV when it supports them, otherwise they become their calculated values.
How long does a XLS to CSV conversion take?+
Most XLS 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.
Is my XLS file kept private during XLS to CSV conversion?+
Yes. Your XLS is processed in an isolated worker, never shared, and permanently deleted from our servers within 60 minutes. Most XLS to CSV conversions happen right in your browser.
Do I need to install anything to convert XLS to CSV?+
No. Converting XLS to CSV runs entirely in the browser – no desktop software, no extensions and no account for the free tier.
What is the maximum XLS file size I can convert to CSV?+
Up to 100 MB per XLS on the free tier and 2 GB on Pro. If your XLS is larger, split it first or upgrade for the higher limit.
