How Sonotube Estimate Exporter Works?

To export an estimate, the Sonotube Estimate Exporter writes your dimensions, quantities and costs into a text or data format another program can open. The process takes 4 steps.

  1. Build the estimate

    Enter tubes, waste, bag size and prices.

  2. Pick a format

    Choose CSV (comma-separated values), JSON (JavaScript Object Notation), plain text, TSV (tab-separated values) or a Markdown table.

  3. Pick the fields

    Select inputs, volumes in cubic feet (ft³) and cubic yards (yd³), bags and costs.

  4. Copy or download

    The tool copies the output to the clipboard or saves it as a file.

Sonotube Estimate Exporter Formula

The Sonotube Estimate Exporter writes one row per tube group and one row of totals.

Row volume

Vᵢ = nᵢ × π × (Dᵢ ÷ 24)² × (Hᵢ ÷ 12)

Written to the ft3 column.

Totals row

V = Σ Vᵢ; Cost = Σ Costᵢ

Last row of the export.

Precision

3 decimals for ft³, 4 for yd³

Keeps the values exact for re-use.

Worked example: CSV for 8 piers at 10 in × 48 in

  1. tube,dia_in,depth_in,count,ft3,yd3,bags_80lb
  2. deck,10,48,8,17.453,0.6464,32
  3. TOTAL,,,8,17.453,0.6464,32

Sonotube Estimate Exporter Conversion Table

CSV is the safest choice for spreadsheets. JSON suits software and automation.

What is Sonotube Estimate Exporter?

A Sonotube Estimate Exporter is a data tool that exports Sonotube dimensions, quantities and costs into reusable text and data formats.

Retyping numbers from a calculator into a spreadsheet invites typos. The exporter writes the estimate once, in a format that spreadsheets, estimating software and scripts read directly. Each row keeps the inputs next to the results.

Exports keep a record of the estimate at the moment it was made, which helps when quantities change later.

What are the uses of Sonotube Estimate Exporter?

There are 4 main uses of the Sonotube Estimate Exporter.

  • Spreadsheet import

    Estimators load CSV rows into a bid sheet.

  • Software integration

    Developers feed JSON into job-costing tools.

  • Quick sharing

    Crews text a plain-text summary to a supplier.

  • Version records

    Offices save each estimate version as a file.
