Frequently asked questions
How do I convert XLSM to XLSX?+
Upload your XLSM file (or drag it onto the box above), wait a few seconds while StandardsPDF converts it in your browser, then download the XLSX. There is nothing to install and no account required.
Is converting XLSM to XLSX free?+
Yes. XLSM to XLSX 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 XLSX keep the quality of my XLSM?+
StandardsPDF aims for the highest fidelity the XLSX format allows, so your spreadsheet comes through looking as close to the original as possible. Some format-specific details may adapt where XLSX works differently to XLSM.
Are formulas kept when I convert XLSM to XLSX?+
Cell values, rows and columns from your XLSM are always preserved. Live formulas carry into the XLSX when it supports them, otherwise they become their calculated values.
How long does a XLSM to XLSX conversion take?+
Most XLSM files convert to XLSX 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 XLSM file kept private during XLSM to XLSX conversion?+
Yes. Your XLSM is processed in an isolated worker, never shared, and permanently deleted from our servers within 60 minutes. Most XLSM to XLSX conversions happen right in your browser.
Do I need to install anything to convert XLSM to XLSX?+
No. Converting XLSM to XLSX runs entirely in the browser – no desktop software, no extensions and no account for the free tier.
What is the maximum XLSM file size I can convert to XLSX?+
Up to 100 MB per XLSM on the free tier and 2 GB on Pro. If your XLSM is larger, split it first or upgrade for the higher limit.
