What the AI produces

Spreadsheets are the most common form of "process documentation" in many companies — converting them to diagrams suddenly makes the flow visible and reviewable.

What is Excel-to-flowchart conversion?

Upload .xlsx, .xls, or .csv files where each row is a step (with optional next-step or yes/no branch columns) and Flowova builds a flowchart from the table. Two table shapes work especially well: simple sequence tables (one row per step) and decision tables with explicit Yes/No next-step columns. Tables that mix process rows with unrelated reference data confuse the extraction — trim the sheet down to just the procedure rows before uploading.

Convert Excel Data to a Flowchart

1

Upload Your Spreadsheet

Upload an Excel (.xls, .xlsx) or CSV file (max 10MB). Best format: each row represents a step, columns can represent step number, description, owner, decision branches.

  • .xlsx, .xls, .csv accepted
  • Up to 10MB on free, 30MB on Pro
  • One sheet per upload — trim to procedure rows
2

AI Interprets Data

Flowova reads the spreadsheet, identifies the sequence (by row order or by a "step number" column), and infers branches from columns named "if yes," "if no," or "next step."

  • Sequence tables (one row per step) work directly
  • Yes/No next-step columns become decision diamonds
  • Mixed reference data confuses the extraction
3

Customize and Export

Refine — spreadsheets often need cleanup because column meaning isn't always obvious to the AI. Theme and export.

  • Edit labels and re-route arrows
  • Export PNG (free) or SVG (Pro) for audit binders
  • Theme for brand or operations context

Three Spreadsheet Formats

.xlsx, .xls, .csv accepted. Up to 10MB on free, 30MB on Pro. One sheet per upload — for multi-sheet workbooks, the first sheet is used by default.

Sequence-Table Shape

Tables with one row per step ("Step #, Description") convert linearly. Optional "Next Step" column overrides the default top-to-bottom ordering.

Decision-Table Shape

Tables with explicit "If Yes" / "If No" columns generate decision diamonds with the named next-step routing — no ambiguity about the branch.

Header Row Auto-Detection

The first row is treated as headers when the cells contain non-numeric labels. Override by adding a blank row at the top before uploading.

Mixed Data Cleanup

Sheets that mix process rows with unrelated reference data confuse extraction — trim down to just the procedure rows before uploading for best results.

Back to CSV via Export

After visual edits, the diagram can be re-exported back to a CSV of (id, label, type, next, condition) — useful for keeping process data in source control.

When to use excel-to-flowchart

Use this tool for

  • A decision table that lives in Excel — one row per step, 'if yes / if no' columns — turn it into a diagram in one upload.
  • Process documentation maintained by an ops analyst in Excel that needs a visual version for the next team review.
  • Auditing decision logic in a spreadsheet for completeness — the diagram surfaces missing branches the analyst overlooked.
  • Bridging analyst-maintained Excel sources with team-shared visual docs without a manual rebuild.

Use a different tool for

  • CSV files that are pure data dumps with no procedural structure — a flowchart isn't the right output for raw data.
  • Cells whose meaning lives in conditional formatting (colors, bold) — the parser reads displayed values only; encode branches in columns instead.
  • Multi-sheet workbooks — only the first sheet is read. Save the relevant sheet as its own .xlsx.
  • Apple Numbers (.numbers) or Google Sheets links — export to .xlsx or .csv from those tools first.
