01 — Format Tables

From messy output
to perfect APA.

Paste from R, SPSS, Excel, or any source. Mellio parses the structure automatically — row roles, column headers, spanning headers — and renders it in your chosen citation style with a live preview as you edit.

03 — Assemble Documents

Write once.
Insert everywhere.

Write your manuscript with simple placeholders like [Table 1] and [Figure 1]. Upload the .docx — Mellio matches each placeholder to your saved tables and figures, then builds the completed document. All client-side, no backend.

Set Row Type
A grouping label that sits above column headers to group several columns together.
The main column labels that name each column (e.g., Variable, Mean, SD).
A label row within the data area that divides results into named groups.
Rows containing your actual results.
Column 1

This row appears after data rows.

Column headers should normally be at the top. Consider using "Section Title" instead.

This row has values in multiple columns.

Converting to Section Title will keep only the first non-empty cell and span it across the full table width.

The destination cells already have data.
