Follow the red arrows and numbered highlights in these screenshots of the actual HeightCompare bulk converter. The measurements and labels shown are examples. Tap a numbered step below an image to zoom directly to that control. Close the screenshot to return to the guide.
Open the bulk converter ↗. The tool’s How to use button opens this guide in a new tab so your current input and results stay in the original tool tab. Return to that original tab to continue; a newly opened tool tab starts a separate empty session.
Import your CSV and choose settings
- Download the CSV template. It provides label,height,unit headers and sample data. Edit it in your spreadsheet app and save as UTF-8 comma-separated CSV.
- Choose a CSV file to import. Select the file picker under Import CSV from your device. Files stay on your device. Import supports up to 1,000 rows and 500 KB.
- Inspect the loaded input. A valid file replaces the input and asks you to convert. Each CSV row can use cm, m, mm, in or ft in its unit column. Labels with commas need double quotes. For a plain list, paste one number per line and choose Unit for plain lists instead.
- Choose result decimal places. Select zero to four maximum decimals. CSV unit columns take priority over Unit for plain lists. Decimal feet use fractions of a foot: 5.5 ft means 5 ft 6 in.
- Convert all heights. The whole list must be valid. Changing input or precision clears stale results until you convert again.
Check mixed-unit results and export
- Check input units and conversions. The highlighted Input unit column shows the original unit for every row. In this example, 170 cm, 1.7 m and 1700 mm are equal. Seventy inches converts to 177.8 cm; 5.5 decimal feet converts to 167.64 cm. Swipe or scroll the table sideways to reach every converted unit.
- Export all results as CSV. The blue Export results CSV button downloads the complete table, including rows not currently visible. Use Save CSV if the download did not start when the browser needs a second tap. Original label, height and unit columns are retained for reimport; extra conversion columns are ignored on reimport. Formula-like labels are protected for spreadsheet opening and restored by this converter when reimported.
Export and read results on a phone
- Tap Export results CSV. It appears above the results table after a successful conversion. Your phone may show a download notification, file preview or save sheet; the exact interface depends on its browser. If needed, tap the Save CSV link the tool adds.
- Swipe within the table. Move sideways inside the white table area to reveal cm, metres, mm, total inches, decimal feet and feet-and-inches columns. The page itself stays within the phone width. All five example rows are included in the export.
If an import fails
A rejected file keeps your existing input and results. Read the error below the form, fix the stated row in the CSV and select the file again. Unknown units, negative or zero heights, duplicate headers, mismatched columns, unclosed quotes and files above 500 KB are rejected. If you manually edit pasted input, the previous export is removed to prevent outdated downloads; fix the input and convert again.
Quick answers
Will opening this guide lose my current list?
No. How to use opens a separate tab and leaves your current tool tab intact. The converter does not automatically save data: reloading or closing the original tool tab can clear its input. Export a CSV to keep a copy.
Can I use a semicolon-separated spreadsheet file?
Save or export it as UTF-8 comma-separated CSV. Use decimal dots in numbers. This converter expects commas between columns.
Why is an old table gone after I changed a setting?
It is cleared intentionally so an outdated conversion cannot be exported. Select Convert all heights to create the updated table.
