# Share a Sigma Dashboard — A Link That Doesn't Need a Sigma Seat

> Sigma workbooks need a licensed viewer or an embed setup. Export the workbook and publish it to Comma for a link anyone can open, with comments anchored to the numbers.

# Share a Sigma dashboard

Sigma is built for people who work in Sigma. The recurring distribution
problem is everyone else: the board member who reads one page a month, the
client paying for the analysis, the vendor who needs their own numbers and
nothing else.

Both official answers — a seat, or an embed integration — are large for a
recurring email.

## Export and render

```bash
# one CSV per workbook element, exported from Sigma
python - <<'PY'
import pandas as pd, pathlib

parts = []
for csv in sorted(pathlib.Path("exports").glob("*.csv")):
    df = pd.read_csv(csv)
    parts.append(f"<h2>{csv.stem.replace('-', ' ').title()}</h2>")
    parts.append(df.to_html(index=False, float_format="%.2f"))

pathlib.Path("sigma.html").write_text(
    "<style>body{font:14px/1.5 system-ui;margin:2rem}"
    "table{border-collapse:collapse}td,th{border:1px solid #ddd;padding:.4rem .6rem}</style>"
    + "".join(parts)
)
PY
```

Then publish it:

```bash
curl -fsS -X PATCH "https://commareports.com/api/v1/reports/$REPORT_ID" \
  -H "Authorization: Bearer $COMMA_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d "$(jq -n --rawfile html sigma.html \
        --arg title "Monthly numbers — $(date +%B\ %Y)" '{title: $title, html: $html}')"
```

## What the published copy adds

- **Anchored threads** — "is this net or gross?" sits on the cell, and the
  answer stays there for whoever reads it next. See
  [commenting on HTML](/comment-on-html).
- **Revisions at one URL** — one report id for the monthly pack; the link in
  the calendar invite never rots.
- **Access per report** — unlisted, domain-gated, team-only, or private. See
  the [sharing model](/docs/sharing).
- **A schedule** — [scheduled HTML reports](/features/routines/scheduled-html-reports)
  publish the refresh for you.

## Limits

- **Entry HTML: 5 MB.** Tables of raw rows get there quickly — aggregate for
  the shared copy and attach the full extract as an asset.
- **Assets: 25 MB per file, 250 MB and 500 files per report.**
- **60 requests/minute per token.**

## Try it

Comma is free — unlimited reports, unlimited commenters, unlimited revision
history.
