Questions
Frequently asked questions
Your data
Does my data go to a server?
No. Rekenblad works entirely in your browser. Whatever you paste or open stays on your own device. The site technically allows no outgoing connections.
Does Rekenblad keep what I paste?
No. Close the page and everything is gone. Your browser only remembers your preferences, such as light or dark.
Do I need to create an account?
No. No account, no email address, no cookies to follow you.
The tools
Is it really free?
Yes. No limit on how often, no ads, no watermark. Rekenblad is a free tool from nealvdv, part of Handig.
Does it work on my phone?
Yes, in a recent browser. Large tables do go more smoothly on a computer, because it has more memory.
Why does Excel open my CSV in one column?
Excel in Belgium expects a semicolon between the columns and a comma as the decimal separator. With CSV to Excel you turn it into a real Excel file; with Excel to CSV you choose the delimiter yourself.
Limits
How big can a file be?
Up to 50 MB per file. Beyond that, many devices run out of memory.
Can Rekenblad open protected Excel files?
No. First remove the password in Excel, using the password you know.
Are formatting and formulas kept?
No. Rekenblad works with values: text, numbers and dates. Colours, borders, formulas and charts don’t come along.
