Why convert WK3 to BMP?
A WK3 file is a Lotus 1-2-3 Release 3 worksheet, the version that introduced several sheets stacked in one file. The BMP shows the worksheet's cells as LibreOffice Calc prints them, with calculated values, number formats and text laid out in rows and columns, sheet by sheet.
BMP stores every pixel uncompressed, so the image is exact and simple to read by any software that handles Windows bitmaps.
Frequently Asked Questions
How do I convert WK3 to BMP?
Drop your WK3 file above and press Convert. Our servers open the Lotus worksheet in LibreOffice Calc, print every sheet to a PDF and render each page as an image. The result is saved as an uncompressed BMP bitmap, ready to download.
Is every sheet of a multi-sheet WK3 included in the BMP?
Yes. Release 3 files can hold several sheets, and each one is printed in turn, so all of them appear in the BMP pages.
Do Lotus @ functions in a WK3 show their results in the BMP?
Yes. LibreOffice Calc reads Lotus formulas such as @SUM and @AVG, and each cell prints its calculated value.
What happens when a WK3 file fills several BMP pages?
Each page is rendered at 144 dpi and saved as its own BMP image, named page-1, page-2 and so on, and they download together as one ZIP. A single page downloads as one BMP file.
What kind of BMP does the WK3 converter create?
A standard Windows bitmap with every pixel stored uncompressed, so the image is an exact copy of the rendered result.
Is my .wk3 file kept private?
Your file is uploaded over an encrypted connection, converted on our servers and deleted automatically within 24 hours. We never read, share or keep your files, and no account is needed.
