Project data health check

Establish what the data can support before choosing a solution. After reading a CSV, confirm columns, units and interval meaning. The tool retains issue evidence rather than silently filling gaps or choosing duplicate values.

CSV and calculations run in this browser; raw CSV is not uploaded. Local drafts are written only when you save, and exclude CSV. An enquiry summary is prefilled only when you choose that action; you still need to submit the form yourself.

Project name or reference (optional)

1. Choose or paste a CSV

Use UTF-8 CSV, at most 2 MB, 50,000 records and 100 columns. Comma, semicolon and tab separators are supported. Numeric values use a decimal point; thousands separators, formulas and Excel date serials are not accepted.

2. Define the data meaning

Timestamp columnPower columnInput power unitExpected interval (minutes, 1–1440)Fixed UTC offset for unqualified timestamps (minutes)For example Singapore +480, Jakarta +420, UTC 0. An explicit Z or ±HH:mm takes precedence; DST is never inferred.What the values representMeaning of signed power

Use a time such as 2026-01-01T00:15:00+08:00. Use interval starts or ends consistently. No external expected start/end dates are supplied, so coverage does not detect missing data before or after the file.
