What this conversion produces
Turn a small API export into an editable spreadsheet without first flattening its values into CSV. Paste an array of records to create one worksheet with a header row. Headers are collected in first-seen order across the records. Text remains text, including leading-zero identifiers and strings beginning with an equals sign; numeric and boolean JSON values become native Excel cells.
Supported input and practical limits
Records must be flat objects containing strings, finite safe-range numbers, booleans or null. Nested arrays and objects require an explicit flattening decision and are rejected. Missing properties and null become empty cells. The table is limited to 50,000 cells and individual strings to Excel’s 32,767-character cell limit. This converter creates a new workbook and does not execute formulas, build charts or preserve a pre-existing workbook template.
Example input
[{"id":"001","name":"Ada","score":95,"active":true},{"id":"002","name":"Grace","score":98,"active":false}]What should I know before converting?
