JAOT

Importing & Exporting Model Files

JAOT speaks the standard optimization file formats. You can import an existing model into the workspace as a first-class, versioned model — and export any model or solve result back out.

Supported formats

FormatImportExportNotes
MPSYesYesThe classic fixed/free MPS format
LPYesYesCPLEX-style LP files
CIPYesYesSCIP's constraint integer programming format
JSONYesYesJAOT's native OptimizationProblem schema
CSVYes (data)Yes (solution)Import tabular data into a problem; export a solution table
SOL--YesSolver solution file for a finished execution

Importing a model

From the studio launcher (New Model), pick Import a file and choose an MPS, LP, CIP, or JSON file. The file is parsed into a model project and the workspace opens on it — from that point it behaves like any model you built by hand: analyze it, solve it, commit versions, publish it.

A very large import (tens of thousands of variables) skips the visual canvas automatically; Analyze and Solve work normally and the model stays editable through the JSON editor.

Datasets have their own import path (.dat / .json / .csv) — see Datasets & Scenarios.

Exporting

  • A model — POST /api/v2/solve/export/model/{fmt} renders any OptimizationProblem as mps, lp, cip, or json — no solve required.
  • An execution — GET /api/v2/solve/export/{execution_id}/{fmt} downloads a finished run as the model (mps/lp/cip/json) or the solution (sol/csv). In the app, export buttons live on the execution detail page, which also offers a printable report.

Via API and MCP

# Preview how a file parses into a problem (nothing is stored)
curl -X POST "https://jaot.io/api/v2/solve/import/preview" \
  -H "Authorization: Bearer ok_live_..." \
  -F "[email protected]"
 
# Import and solve in one step
curl -X POST "https://jaot.io/api/v2/solve/import" \
  -H "Authorization: Bearer ok_live_..." \
  -F "[email protected]"
 
# Export a model as LP (no solve)
curl -X POST "https://jaot.io/api/v2/solve/export/model/lp" \
  -H "Authorization: Bearer ok_live_..." \
  -H "Content-Type: application/json" \
  -d @problem.json -o model.lp
 
# Export a finished execution's solution as CSV
curl "https://jaot.io/api/v2/solve/export/exec_abc123/csv" \
  -H "Authorization: Bearer ok_live_..." -o solution.csv

The same operations are available as MCP tools: import_preview, import_and_solve, export_model, and export_execution — see the MCP Overview.
