The spreadsheet knows the date.
It just never calls.
A spreadsheet is the world's most popular CRM — until the first forgotten customer. How to spot that day, and how to move without losing data.
This is how a spreadsheet dies.
From spreadsheet to Lemnio in an afternoon.
One row = one person or company. Unify the columns, save as CSV in UTF-8 so special characters survive.
Leave dead contacts and duplicates in the sheet. The system is for living customers and promising inquiries.
Give your twenty most important customers a date and a reason for the next step. From then on, the data speaks up on its own.
CRM instead of spreadsheets
Why every spreadsheet eventually stops being enough
Three signals: you stopped opening it (the data is there, nobody looks), several versions exist at once (two versions of the truth), and you need the data to alert you — which a spreadsheet cannot do by design. A reminder lives or dies on one thing: it has to come to you.
What you gain over the sheet
Reminders that speak up on their own. A history a colleague can find while you are on vacation. One version of the truth for the whole team. And it still holds: the data is yours — export it back to CSV anytime.
Questions when leaving the spreadsheet.
Does my sheet have to be perfectly clean?+
No — unify the columns and save as CSV. Order emerges inside the system; the big cleanup beforehand is the most common reason migrations never start.
What will it cost me to start?+
The free plan covers 100 companies and 200 contacts forever — plenty for a first migration. You pay only once your customers outgrow it.
Can I get my data back out?+
Yes, anytime and completely, to CSV. If Lemnio does not fit, you leave with everything you came with — plus the history.
What about the original spreadsheet?+
Stop maintaining it. Two versions of the truth are worse than one — pick the system and keep the sheet as an archive.
Trade the spreadsheet for memory.
