She sewed the flag that represented the liberation of Dumbeni (today Dendrochori), Kastoria from the Ottomans and was the flag-bearer for her unit during the Ilinden Uprising.

She and a fellow teacher, Elena Minasova, sewed and bore the flag representing the movement to liberate Dumbeni.

Grancharova was arrested by Turkish authorities and imprisoned in Korçë (today in Albania) along with fellow revolutionaries Manol Rizov, Lazar Poptrajkov, and Pavel Christov.

On 2 August 1903, at the start of the uprising, Grancharova rode on horseback, carrying the flag next to her commander, Manol Rizov.

She was buried as a heroine, and in 1997, her gravestone was adorned with a commemorative plaque with a photograph depicting her in full guerrilla attire.
