Practical guides
Practical Rakuruno workflows for text cleanup, PDFs, QR codes and business-day counting, with examples and checks before you use the result.
Go directly to a tool to start working, or choose a guide below when you need help with assumptions, workflow or checking the result.
Clean an Excel list: whitespace, character width, then duplicates
Follow three fictional product codes through whitespace cleanup, full-width conversion and deduplication, with checks before pasting back into Excel.
Check where a PDF merger processes files before using a work computer
Use fictional PDFs to verify Rakuruno’s local merging workflow, distinguish file processing from page traffic, and identify cases that need an approved workplace tool.
Do free QR codes expire? Check the code and its destination separately
See what Rakuruno stores in a static QR code, distinguish code expiry from a changed destination, and check a saved code before printing.
Turn multiple images into one PDF in the order you checked
Arrange a cover and two body images, generate and inspect a three-page PDF, and understand image quality, transparency and size limits.
When is five business days later? Define the start day and holidays first
Count five business days from a Friday, then add a fictional company holiday and verify the candidate end date using Rakuruno’s date-range calculator.
What browser-local processing means: input, storage and network traffic
Distinguish Rakuruno’s on-device processing, 30-day drafts and page or Analytics traffic, with practical checks for shared computers and tool-link sharing.
