How to create a flowchart from a spreadsheet
If your process already lives in a spreadsheet (a checklist, a procedure, a list of steps someone keeps in Excel), you do not need to redraw it box by box. Structured the right way, the spreadsheet is the flowchart: each row becomes a step, and the diagram can be generated from it.
Why start from a spreadsheet
Drawing a flowchart by hand means placing boxes, routing arrows, and fixing the layout every time a step changes. A spreadsheet is faster to write, easier to review with colleagues, and simple to keep up to date. Generating the diagram from the rows keeps the two in sync: change a cell and the chart changes with it.
It is the same idea OrgTree.app uses for org charts, where a list of people with their managers becomes an org tree. For processes, the list is steps instead of people.
Structure the spreadsheet
Use one row per step, in the order the work happens, with a few columns:
- Step: a short action, starting with a verb, such as "Check the invoice".
- Who: the role or department that does the step. These become the swimlanes.
- Type: an ordinary step, a decision (a yes/no question), or the start and end.
- Next step: where the flow goes next, and for decisions, where each answer leads.
Turn it into a process map
With the steps in that shape, a spreadsheet-driven editor can draw the flowchart for you, lanes and all. Our sister tool ProcessMapping.app does exactly that: paste the rows and the swimlane process map lays itself out, free and with no signup.
Connect it to your org chart
The Who column of a process is usually the roles or departments on your org chart. Building the org chart first gives you the lane names, and makes it obvious who owns each step. OrgTree.app draws that org chart from a people list in the same way.
Frequently asked questions
Can Excel make a flowchart from data automatically?
Not on its own. Excel can hold the steps, but you need a tool that reads the rows and draws the diagram, such as ProcessMapping.app for swimlane process maps.
What columns does a flowchart spreadsheet need?
At minimum a step description and the order of steps. Adding who does each step gives you swimlanes, and a type column lets decisions be drawn as diamonds.

The editor is free and opens with a starter org chart. One row per person, and the chart draws itself as you type. No signup required.
